## History

### Early Life

Pursues 'Percy' Jackson, was born on August 18th to Poseidon, and Sally Jackson, a mortal with the ability to see through the mist. He was named after a famous Greek hero Pursues by his mother for good luck, because his namesake was one of the few heroes who had a happy ending and died a peaceful death.

Before Percy was born, his father left, as the gods usually do. He left to protect Percy and his mother from Zeus, who would get angry if he discovered that Poseidon had broken The Pact of The Big Three. When Percy was a baby, he was attacked by a snake, and managed to strangle it to death like the. famous Roman demigod, Hercules had. Poseidon occasionally visited Percy while he was in his cradle. Percy has described his father's warm smile and a hand on his head as a "golden glow". When Percy grew older, his mother would him his father had been 'lost at sea.'

### Smelly Gabe

When Percy was just a toddler, his mother Sally married a man named Gabe Ugliano, hoping that his horrid smell would mask the scent of her son from the monsters that would hunt him, as monsters can smell the scent of Demigods. The more powerful the Demigod, the stronger the scent, and since Percy was a son of one of the big three, his scent was stronger than other demigods. Percy hated Gabe, and Gabe would often bully Percy, and Abuse his mother. Percy nicknamed him 'smelly gabe,' because he smelled like "moldy garlic pizza wrapped in gym shorts." Gabe spent most of his time drinking, and playing poker with his friends.

### Early School Life

When Percy was young, strange things would often happen around him. Including a School bus exploding, and an aquarium being flooded. These things often resulted in him getting into trouble, and getting kicked out of schools. In total, he was kicked out of 6 schools, in 6 years. Many people bullied him. Including Nancy Bobofit, as seen in the first book.

When Percy was in third grade, a large man followed him around at school. By threatening to call the police, the teachers got the man to leave. Nobody believed Percy when he said the man had only one eye. They all thought that he was Hallucinating.

When Percy was in fourth grade, while on a school trip to an aquarium, he accidentally hit the wrong lever on the catwalk, making his class take an "unplanned swim"

In the fifth grade, Percy accidentally fired a war cannon, which hit the school bus when he was on a field trip at the Saratoga Battlefield.

## Percy Jackson and the Olympians

### The Lightning Thief

Percy is a troubled. 12-year-old boy, with ADHD and Dyslexia. He has been expelled from every school he has ever attended. Who he arrives at Yancy Academy, his troubles seem even worse then usual. He only has one friend, Grover Underwood, who is Percy's best friend, and Percy protects Grover from bullies. During a class field trip to a museum, the school bully, Nancy Bobofit, is bullying Grover. Percy, in a fit of anger, accidentally summons water from a fountain to grab her, and pull her in, but Percy doesnt know how he did it. Mrs. Dodds, Percy's pre-Algebra teacher witnessed the whole thing and told Percy to follow her into the museum for a 'talk.' Inside, she turns into the Fury Alecto, and attacks him looking like a bat with humongous fangs. Mr Brunner, on of Percy's other teachers, comes in and throws Percy a pen that transforms into a sword that Percy uses to kill Mrs. Dodds. When Percy returned to the class, and asks his classmates, nobody remembered Mrs. Dodds. Everyone believed their teacher was instead Mrs. Kerr. Percy arrives back at the school and hears Grover and Mr. Brunner talking about his life being in danger and becomes very suspicious since extremely strange things have been happening recently. Percy takes his finals, and gets kicked out of the school yet again. Percy and Grover go home on the same bus. At the bus stop, Grover sees that the three Fates are looking at Percy while knitting giant socks. Soon after, the Fates snip the string of life which makes Grover very worried that Percy was going to die soon, and Percy extremely suspicious. Later, while Grover was in the bathroom, he ditched Grover and goes home on his own. even though Grover asked him to wait for him at the bus stop, because Grover was giving off weird vibes.When Percy arrives home, his step-dad Smelly Gabe, and his friends, were playing poker. Gabe demands money for his poker game, and even though Percy denies he had any, Gabe decides that he has change from the cab driver and makes Percy hand it over. Percy's mother gets home and tells him they are going to his favorite beach in Montauk for a whole weekend. Percy was happy something good had finally happened, and quickly packed his bags and they left, but not before seeing Gabe get hit in the butt by the door when he does a strange hand gesture he saw Grover use. During their night in Montauk, Percy had a vivid dream. The dream features two animals, which is a horse and a bird attacking each other. At the same time, there is a voice, that Percy describes as so deep and evil that it turned his blood to ice, egging the two animals on. Percy was awoken by the pounding of the door. He and his mother are shocked to see Grover outside their cabin, without pants, telling him and his mom they had to leave. Percy was confused at Grover's appearance, and the fact that he was a goat from the waist down, what was called a satyr. Percy's mother takes them both in Gabe's prized possession, a 1978 Camaro, and began to drive at dangerous speeds through a blinding hurricane. The car was blasted off the road by a bolt of lightning. Grover as injured, and started asking for food, deliriously. Percy and his mom helped Grover up and tried to get out, they saw the Minotaur. A half-man, Half-bull monster, that had been chasing them. The three manage to dodge it by following Sally's advice of jumping out of the way at the last second, but Grover was too slow and the Minotaur injured him, but then got distracted by Percy's mother. The Minotaur forgot Grover, and grabbed Percy's mom by the neck. She disappeared in a golden flash of light, which was her being captured by Hades. In a burst of power, Percy defeated the Minotaur by jumping on him, breaking his horn off, and stabbing it in the chest. Percy dragged the unconscious Grover past a hill, and then passed out himself when he reached the porch of a house. He was cared for in the infirmary by Annabeth Chase starting their friendship, waking up three days later. He learned that he was at Camp Half-Blood, a place where demigods like him were trained to survive against monsters. Percy learned that the director of the camp was the greek god of wine, Dionysus. He was very unpleasant, and moody. The camps hero-trainer, the centaur Chiron, was actually Percy's teacher, Mr. Brunner. He met a girl named Annabeth his new friend from the Athena's Cabin, he found out that all the campers were demigods, also known as half-bloods. He himself was a demigod, but no one knew of his divine father yet. After being shown around the camp, he temporarily resided in the Hermes' Cabin, where all unclaimed demigods went since "Hermes isn't picky about who he sponsors," according to Luke Castellan, the head counselor for this cabin. Luke befriended Percy and treated him with respect though they had a little bit of rivalry after Percy beat Luke in a sword fighting match. Afterward, Percy encountered Clarisse La Rue, counselor of the Ares' Cabin, who performed the "initiation ceremony," which was sticking Percy's head in the girl's bathroom toilet. Her plan backfired when Percy shot water out of the toilet to blast back at Clarisse and her buddies. This officially began their rivalry. Unfortunately, Annabeth was not spared. When Percy apologizes, Annabeth says he wants her on her team in Capture the Flag (it is revealed that she wanted Percy to distract Clarisse, knowing she would want revenge). Throughout the course of this game, Percy defeated Clarisse and three others single-handedly when he touched the creek, which healed his wounds from the fight and gave him a sudden burst of adrenaline. After Capture the Flag, a hellhound summoned from the Fields of Punishment, came out of the forest and attacked him. Percy was nearly killed but Chiron managed to shoot the hellhound, killing it. Clarisse tried to blame Percy for summoning the hellhound but Percy denied any knowledge of it. Percy's injury from the hellhound healed by touching the water; then suddenly, a holographic trident floated above Percy's head, which told everyone that he was the son of Poseidon, the god of the sea, therefore explaining his powers over water. As the monster was not from the forest, it meant that someone within the camp had summoned it, because nothing, including weather, could enter the camp's magic boundaries without permission. Clarisse said that it was Percy who summoned it but Chiron didn't agree as Percy himself was attacked by the monster (it is later revealed Luke summoned this monster from Tartarus to kill Percy). One day, Percy was offered a quest to retrieve Zeus's Master Bolt by Chiron. Chiron explained to Percy that Zeus lost his master bolt, and since he has a rivalry with Poseidon, he blames Percy, as Zeus suspects that Poseidon is attempting to use his son to dethrone him because Percy was at New York (where Mount Olympus was) when the Bolt was lost. He believed that Poseidon told Percy to get the bolt since it is against the Ancient Laws to steal another god's symbol of power, so he could become king of the gods. Zeus was also suspicious as Percy was in New York when the bolt disappeared. Chiron said that if Zeus doesn't get his bolt back by that summer solstice, he would begin a war with Poseidon and that would force the other gods to take sides and cause a civil war between the gods. Percy accepts the quest and consults the camp's Oracle of Delphi and getting a prophecy. Soon after learning that Master Bolt has been stolen, Percy embarks a quest with his sword Anaklusmos, better known as Riptide (from Chiron), with Grover and Annabeth. Along the way, they face many monsters—the Furies, Medusa, Echidna, along with her pet/son Chimera. Percy took Medusa's head after he defeated her and packaged it to the gods, who weren't very pleased. After Ares offers them a mode of transportation west, they arrive in Las Vegas, where they stumble upon the Lotus Hotel and Casino. They get trapped in the casino for five days (though it only seems like a few hours), leaving them only one day to complete their quest. Then, they faced Procrustes and tricked him into getting stretched in his old bed before finding their way to the Underworld. The trio faces Hades, the lord of the dead, who believes Percy stole the Master Bolt and his Helm of Darkness, which was also lost. Hades saved Percy's mother right before she died from the Minotaur, explaining the golden flash but Hades also thought that Percy stole his Helm of Darkness which was also missing. To make things worse, Hades finds the bolt in Percy's backpack, to Percy's surprise and demands that he hands it over and he will give Percy his mom back. Torn between saving his mom and finishing the quest, Percy finally uses Poseidon's Pearls to find the missing gods' items. Immediately returning from the Underworld, he finds out that the war god Ares had put Master Bolt in the bag when and had Hades' Helm of Darkness, and challenges the god to a duel for possession of the bolt and the helmet, in which he wins unexpectedly due to him being close to water and Ares being too cocky. A dark force later revealed to be Kronos stops an infuriated Ares from killing Percy. Ares vanishes in his divine form, leaving the bolt and Helm of Darkness behind. Percy gives the helm to the Furies to return it to Hades, who in return sends back Sally to her apartment, and the trio goes to New York to return the bolt to Zeus. Percy gives Medusa's head to Sally, who uses it to turn Gabe into a statue which was covered as a sculpture.  Percy goes back to Camp Half-Blood, where everyone at the camp congratulates him, Annabeth, and Grover since they were the first people to return from a quest since Luke. At the end of the summer, Percy can't decide whether to stay at camp or enroll in seventh grade and live with his mom. He finally decides to go train to clear his mind, where he sees Luke training at swordplay. As they later drink Coke together in the forest, Luke reveals he was behind the theft of the bolt and the Helm of Darkness, and vanishes. However, before he left, he summons a pit scorpion to kill Percy. Percy manages to kill it, but it stabs its stinger into Percy's palm. He tried to reach the camp but collapses. However, several forest nymphs carry him and after being fed ambrosia and nectar, Percy heals and decides to enroll in the seventh grade and come back to camp next summer.

### The Sea of Monsters

Thirteen-year-old Percy Jackson’s strange dreams tell him something’s wrong at Half-Blood Hill, a summer camp for demigods. He also receives desperate midnight messages from his satyr friend, Grover. Annabeth, a half-human, half-god camper, similar to Percy and Grover, appears at Percy’s school and confirms his fears. She saves him from a gang of monsters trying to slaughter him on the dodgeball court. Then she delivers him and his hulking new friend, Tyson, to Half-Blood Hill.  Percy, Tyson and Annabeth find the camp in chaos. Monsters are attacking, and campers desperately try to defend themselves. When Zeus’ daughter Thalia turned into a tree six years earlier, her spirit protected the camp from monsters. Now, someone has poisoned Thalia’s tree. Percy’s mentor, a centaur named Chiron, has been blamed and fired from Half-Blood Hill. A spirit from the fields of punishment named Tantalus has assumed Chiron’s position as assistant camp director.  Annabeth reveals that Tyson is a Cyclops, and Poseidon himself claims Tyson as his son (and Percy’s half-brother). Percy and Annabeth ask the camp leaders for permission to seek the Golden Fleece, which they believe will heal Thalia’s tree. The leaders give the quest to another camper, a belligerent daughter of Ares named Clarisse. Urged on by Hermes, the messenger god, Percy, decides to find the Fleece himself. Annabeth and Tyson join him on this unauthorized journey.  The trio lands on a cruise ship, only to find Luke, a former camper and Percy’s nemesis from the first book in this series, The Lightning Thief, is its captain. He is recruiting half-bloods to help him start a new civilization with Kronos at the helm. Kronos, the Titan king and enemy to the gods, was previously cut into pieces but re-forms a little each time a half-blood joins Luke’s army.  After escaping from Luke and subsequently battling a multi-headed monster, Percy, Annabeth and Tyson are saved by Clarisse. They all sail on her ghost ship full of dead Confederate soldiers toward the Sea of Monsters (i.e., the Bermuda Triangle) in search of Grover and the Fleece. As they enter the Sea, monsters attack the ship. Percy and Annabeth, thinking they’re the sole survivors, sail into the lair of Circe, where Percy is temporarily transformed into a rodent by the man-hating sorceress. They escape once more and sail toward the island of the Sirens. Annabeth desperately wants to hear them. She asks Percy to tie her to something so she can listen but not be lured by their songs. Percy plugs his own ears with wax. Annabeth is so mesmerized that she cuts her way out of her ropes and swims to the island. Percy narrowly saves her.  Percy and Annabeth reach the island of the Cyclops Polyphemus, where they find both Grover and the Fleece. They also discover that Clarisse and Tyson are alive. The heroes battle and trick the Cyclops, escaping with the Fleece. In keeping with the prophesy Clarisse received from the Oracle, the group sends her back to camp via airplane with the Fleece. Luke recaptures Percy, Annabeth, Grover and Tyson. Then Percy sends a message telling the Half-Blood campers that Luke poisoned Thalia’s tree. Chiron and his relatives save Percy and friends, returning them to camp where Chiron’s name is cleared and he is reinstated. The Fleece heals Thalia’s tree, and Thalia herself emerges from the tree as the half-blood she once was.

### The Titans Curse

Percy Jackson, half-mortal and half-Greek god, has known his demi-god (or “hero”) status for several years. As the son of Poseidon, the sea god, he’s already gone on several quests to aid and rescue gods or other half-bloods. He spends his summers at Camp Half-Blood, where he and other heroes find magical protection from monsters and learn how to cope with — perhaps even embrace — their unusual heritage.  In The Titan’s Curse, Percy and his half-blood friends Thalia, daughter of Zeus, and Annabeth, daughter of Athena, respond to a distress call from their satyr friend, Grover. Grover has found a pair of half-blood siblings, Nico and Bianca, at the school where he pretends to be a student. He fears a monster, a manticore posing as a teacher, has discovered them as well. As the heroes try to rescue the kids, the manticore tells Percy that the Great Stirring (of monsters) is underway. One monster will even cause the downfall of Olympus, he says. The goddess Artemis and her Hunters arrive to assist the heroes, and they recruit Bianca to join their sisterhood. The manticore captures Annabeth and disappears. When Percy tells Artemis about the manticore’s prophecy, she puts her second in command, Zoe, in charge and leaves to hunt the monster.  The heroes and Hunters return to Camp Half-Blood. They know the stirring of monsters means Titan King Kronos, hated father of the gods whom the gods cut into many pieces long ago, is regenerating and regaining strength. He’s using Luke, a former camper and friend of Thalia and Annabeth, to draw as many half-bloods as possible to his team. Zoe and Percy both have dreams leading them to believe that Annabeth is alive and that Artemis has been kidnapped. The Oracle of Delphi, a mummy who lives in an attic at the camp, issues a prophecy and the camp leaders send Zoe, Bianca, another Hunter named Phoebe, Thalia and Grover to find Artemis. Percy secretly follows them and is discovered when he saves them from the attacking Nemean Lion.  Percy and the others go to New Mexico, where they fight evil skeletons. Pan sends them a wild boar (the Erymanthian Boar) that takes them on its back to the junkyard of the gods in Arizona. When Bianca removes something from the junk heap, a monster appears and takes her. Fearing that Bianca is dead, the group sadly moves on to the Hoover Dam, where the skeletons attack again and statues come to life to fly them to San Francisco. There, they find a sea cow called the Ophiotaurus, which, according to prophesy, will bring great power to whomever sacrifices it. The manticore appears and tells Thalia that since she’s a child of one of the Big Three gods (Zeus, Hades and Poseidon) and is about to turn 16, she can sacrifice the sea cow, bring an end to Olympus, and have great power if she chooses. Thalia is momentarily tempted, but Percy helps her escape while Grover takes the Ophiotaurus to safety.  Percy, Zoe and Thalia find Artemis and Annabeth being held captive by the Titan forces. Atlas, the head Titan general, is also Zoe’s father. He’s forcing Artemis to hold up the weight of the world, which is the Titan’s Curse. Percy temporarily takes it from her so she can battle Atlas. Luke appears and urges Thalia to join him in overthrowing Olympus. After a battle, Zoe dies at her father’s hand, Luke vanishes and the weight of the world is returned to Atlas’ shoulders. Thalia and Percy, having rescued Artemis and Annabeth, meet with the gods. Grover is already there with the Ophiotaurus, which the gods agree to keep in protective custody. The heroes attend a lavish party.

### The Battle of the Labyrinth

Percy Jackson, half-mortal and half-Greek god, has known his demi-god (or “hero”) status for several years. As the son of Poseidon, the sea god, he’s already been on several quests to aid and rescue gods or other half-bloods like himself. He spends his summers at Camp Half-Blood, where he and other heroes find magical protection from monsters and learn how to cope with — perhaps even to embrace — their unusual heritage.  Ninth grade begins badly for Percy, who discovers the cheerleaders at his new school are she-demons called empousai. Their appearance proves that Kronos, leader of the Titans whom the gods cut into pieces, is rapidly re-forming. Kronos is recruiting monsters and half-bloods to battle the Olympian gods.  Percy and his half-blood friend Annabeth return to camp to warn the others. Percy meets the mysterious new sword instructor, Quintus. He learns that his best friend, Grover, is running out of time to save Pan, the missing god of the wild. Annabeth has a theory: Since they can’t find Pan above ground, maybe he’s trapped underground in the Labyrinth created by the ancient genius Daedalus. The expansive maze is supposed to contain dangerous illusions and insanity-causing traps. When Percy and Annabeth find a portal to the Labyrinth on the camp’s land, they’re convinced Kronos and his army will attack through it. With Grover and Tyson (Percy’s Cyclops brother), they enter the Labyrinth in search of Daedalus. They want to ask him for Ariadne’s string, the only tool with which they can safely navigate the Labyrinth.  Meanwhile, Percy dreams about Nico, son of Hades. Nico blames the death of this sister, Bianca, on Percy and seeks revenge. The spirit of King Minos, with his own vendetta against Daedalus, assists Nico.  In the Labyrinth, the group saves the Hundred-Handed-One (Briares) from one of Kronos’ monsters, gets advice from the goddess Hera and stops a three-bodied creature named Geryon from mistreating sacred cattle. They find Nico and help him summon Bianca’s spirit. Bianca urges Nico to forgive Percy. They visit the god Hephaestus, who says he’ll lead them to Daedalus if they will investigate what has invaded his workshop beneath Mount St. Helens. Grover and Tyson search for Pan while Percy and Annabeth enter the volcano and find creatures called telekhines. Percy blasts out of the volcano and lands on Calypso’s island, where she nurses him back to health. Hephaestus helps Percy get back to camp, where he walks into his own funeral. Annabeth, pleased to find Percy alive, tells him Quintus has disappeared.  Percy enlists help from Rachel Elizabeth Dare, a mortal from the last book, because she can see through the Mist. She guides them to Daedalus (who is actually Quintus). They beg Daedalus to help them, but he has already given Ariadne’s string to the Titan army. Nico arrives to save them from the approaching King Minos.  Once reunited with Grover and Tyson, the group finds Pan. Pan is dying because humans no longer cherish the wild. He tells Grover and the others that they must carry on his message when he dies. The kids return to camp and join the other half-bloods in battling the Titan forces. Daedalus and the Hundred-Handed-One show up to help ensure victory.  Back at Percy’s home, Poseidon appears at Percy’s birthday celebration. He tells Percy, “You are my favorite son.” Nico arrives later and tells Percy he knows how they can beat the Titan army for good.

### The Last Olympian

Percy Jackson, half-mortal and half-Greek god, has known his demi-god (or “hero”) status for several years. As the son of Poseidon, the sea god, he’s gone on several quests to aid and rescue gods or other half-bloods similar to himself. He spends his summers at Camp Half-Blood, where he and other heroes find magical protection from monsters and learn how to cope with — perhaps even embrace — their unusual heritage.

The long-anticipated war between the Titans and the Olympian gods begins. Percy, nearly 16, and a fellow camper named Beckendorf intercept a ship carrying some of the Titan army and its leader, Lord Kronos. Kronos, birth father and nemesis of the gods, has inhabited the body of a half-blood dissenter named Luke. Beckendorf dies when he and Percy blow up the ship, but Kronos survives. Percy escapes underwater to see his father, Poseidon, and his Cyclops brother, Tyson. He considers joining the battle they’re waging to preserve the seas, but Poseidon urges him to return to Camp Half-Blood and help fight Kronos.

At camp, Nico, son of Hades, tells Percy they need to understand their enemy before they can fight him. Nico takes Percy to Luke’s childhood home, where they meet Luke’s mother. She once had an ability rarely found in mortals, to “see through the Mist” and view gods and monsters as they really are. When Luke was small, his mother tried to use her gift for good by becoming a physical host for the Oracle of Delphi’s disembodied spirit. But Hades had placed a curse on the Oracle, which made this impossible and left Luke’s mother insane. Luke’s bitterness at his father, Hermes, for not saving him from a crazy mother drove Luke to side with Kronos. Nico and Percy also meet Hestia, goddess of the hearth and “the last Olympian” who surrendered her position of power to keep the peace amongst her siblings. Her visions help them discover that, like Luke, Percy must get his mother’s blessing and then bathe in the River Styx so he can become invincible.

After doing this, Percy returns to New York City. Through an elevator at the Empire State Building, he and his army of campers reach modern day Olympus — the city they must defend. Though the gods are largely unwilling to help in battle, they offer visions and warnings. Back in Manhattan, Percy and the others (including his friends Grover, a satyr, and Annabeth, the daughter of Athena) fight many battles against Kronos’ monsters while the mortals of the city sleep under the spell of Morpheus. Percy receives visions about Nico’s past and cryptic messages from Rachel Dare, a girl who also can see through the Mist, in his dreams. At each point, when the battle seems most bleak, another unexpected god or hero joins the war to defend Olympus. Kronos is finally defeated when Annabeth reminds Luke, still trapped deep inside his own body, that he promised they would always be family. Luke summons the strength to overthrow Kronos, though he has to kill himself to do it.

After the battle, the Olympian gods offer Percy the honor of becoming immortal. He refuses the gift but asks for the gods’ promise to claim and interact with their mortal children from this point forward. The curse on the Oracle is reversed, and Rachel Dare becomes the new Oracle of Delphi. Percy and Annabeth cement their relationship with a kiss as they prepare to remodel the city of Olympus and interpret a new prophecy.

## The Heroes of Olympus

### The Lost Hero

Percy does not appear in this book, but it is revealed that he and Annabeth are officially dating and that the whole of Camp Half-Blood was extremely worried about him. For most of the book, his location was unknown with the only clue being that he disappeared around the same time that Jason Grace, a son of Jupiter, first physically appeared.  It is eventually revealed that Jason and Percy were exchanged by Hera/Juno to unite the demigods of Greece and Rome against Gaea and the Gigantes as well as other creatures.Even though Percy does not appear in this book, it is revealed that he and Annabeth are officially dating and that the whole of Camp Half-Blood was extremely worried about him.

### The Son of Neptune

Percy Jackson has spent three days battling the snake-haired ladies, and frankly, he wishes they’d just stay dead. No matter how many times he’s killed the gorgons, they turn up several hours later, ready to battle him again. To top it off, he’s found himself in San Francisco with no memory of how he got there and only a dim memory of his past. He does remember his girlfriend, Annabeth, and waking up in Wolf House about two months ago. But that is all.  When he awoke in Wolf House, he’d been given a magical pen that turns into a bronze sword. The sword is named Riptide. Then Lupa, the leader of the wolves, gave him instructions. As strange as a talking wolf had been, Percy knew that this weird reality of monsters and demigods, of which he was one, was true.  As Percy escapes from the gorgons for the umpteenth time, he spies a maintenance tunnel guarded by two Roman soldiers. Something tells him that this is where he’s supposed to go, but it means crossing a busy divided highway to get there. An old woman appears, looking like a deranged hippie, and tells him that his suspicions are correct. He needs to go to the tunnel because it’s actually the entrance to a camp. The old woman, called June, gives Percy a choice. He can leave her here, at the mercy of the gorgons, and run to the ocean where he’ll be safe for eternity; or he can carry her with him into the camp.  If he leaves June, then the gods will die, everyone he knows will die, and the earth will be destroyed. Percy opts to carry June to the camp. The closer he gets, the heavier June becomes, but he struggles to complete the task. The Roman guards, who are teenagers like Percy, are named Hazel and Frank. They help him evade the gorgons who have followed him into the tunnel. When they get to a river, June informs Percy that if he crosses the river, he will lose his invincibility. If he doesn’t cross, the world will end.  Thinking of Annabeth, Percy carries June across the river to the Roman camp just beyond it. The gorgons capture Frank. Percy then commands the river water to fight the gorgons so they are forced to release Frank. Once they reach the other side, June transforms into the goddess Juno and informs everyone at the camp of Percy’s identity. He is the son of Neptune. She also warns that if the god of death is not released by the Feast of Fortuna, then they will not be able to defeat their enemies.  Octavian, the camp’s auger, looks for messages in the stuffing of toy animals. Hazel brings Percy to meet him in hopes that he will divine whether the gods will allow Percy to join the camp. While there, Percy reads part of a prophecy written on the temple floor. He vaguely recognizes it. It is the Prophecy of the Seven. It states that seven demigods must battle to the Doors of Death.  Octavian informs Percy that bad things happen to anyone who’s tried to discover more about the prophecy. Octavian sacrifices a stuffed panda bear on Jupiter’s altar and states that Percy may indeed join the legion. He then tries to blackmail Hazel into voting for him for praetor, one of the leaders of the camp. Hazel argues that the old praetor Jason may still be alive, even though he disappeared several months earlier.  On the way to dinner, Hazel and Percy meet up with her brother Nico, another child of Pluto, as is Hazel. Percy is pretty sure he’s met Nico before but can’t remember where or when. Hazel and Nico explain the real danger in all the weird things that have been happening lately: Monsters they kill, like the gorgons, don’t stay dead.  Before they can discuss things further, Frank arrives to help Percy settle into the camp. At dinner, Percy is accepted into the Fifth Cohort, the same division of soldiers as Frank and Hazel. At battle games that evening, Percy helps Frank and Hazel lead their army to their first victory in several years. Before they can celebrate their success, their leader, Gwen, is carried out of the battle on a stretcher — dead. She’s been stabbed through the back. But, miraculously, she returns to life. She tells of seeing a river and a ferry man asking her for a coin, but she simply turned around, exited through an open door and returned to the camp.  A voice rumbles through the camp declaring that death has lost its hold. The god Mars appears on the training field. He explains that Thanatos, the god who guards the gates of death, has been chained. Gaea, a kind of mother earth god, is allowing the dead to come back to life. She is also raising an army to destroy the Roman camp and the world. Mars orders a quest be undertaken to free Thanatos who, unfortunately, is being kept in Alaska, a land where the gods have no power. Thanatos is chained and guarded by a giant — Alcyoneus, Gaea’s most powerful child. The quest must succeed by the Feast of Fortuna in four days’ time.  Mars openly declares Frank his son, much to Frank’s dismay, and orders him and Percy to head the quest. Frank picks Hazel as the third member of their group. Octavian, who is threatened by their new positions of power, insists that they need to start the quest immediately and without any aid, as the camp itself will be under attack soon.  Reyna, the camp’s remaining praetor, brings Percy in for a private talk before he leaves. She and her sister, Hylla, met and fought Percy four years earlier. She warns Percy that the Roman demigods don’t trust anyone Greek. There have been rumors of Greek and Roman demigods battling in the past, but she has no proof of it. Reyna offers Percy the other praetor position, but he turns it down. She asks him to reconsider if he survives the quest. Reyna knows that a powerful army, led by another giant, is going to attack the Roman camp on the Feast of Fortuna. She needs another praetor at her side to help her lead their troops into battle. Reyna asks that Percy find Hylla, who now leads the Amazons, and ask her to join in the fight. Reyna gives him her ring to show Hylla, as proof of his friendship with her.  Percy, Frank and Hazel take all that is left of the Roman navy, a little dinghy, and head toward Alaska. Hazel experiences one of her blackouts. She once was dead, but Nico snuck her through Death’s Gates so she could live again. She periodically slips back into memories of her first life. In it, her mother, Marie, made a rash wish for all the wealth under the earth. Now, gold, silver and precious stones appear where Hazel walks. Anyone who takes the gems however, experiences bad luck. Marie became a servant of Gaea as a way to punish Pluto for his “gift,” and fled to Alaska. Gaea used Hazel’s powers to make a body for her son, Alcyoneus. At the last moment, Hazel betrayed Gaea, killing her mother and herself, rather than allow Alcyoneus to come to life. When they can’t wake Hazel, Frank and Percy take her ashore.  After she wakes, Percy returns to the boat to get her a drink. Frank admits that he’s figured it out; she was once dead. Hazel is relieved that he doesn’t reject her for it. When she is alone, a field of grass creatures attacks her. Hazel uses her powers to call up a boulder from the ground to stop her kidnappers. The servants of Gaea, grain spirits, cannot move over the rock. Percy and Frank arrive in time to save her. From atop the rock, they spy an army of Earthborn, Cyclops and centaurs being led by Polybotes, a giant moving toward the Roman camp. Percy knows this is the army being sent to destroy it.  The friends receive help from Isis (the goddess of rainbows) at a health food store, but before they can continue their journey, Frank must battle three basilisks. He strikes the spear his father, Mars, gave him on the ground. A strange skeletal creature appears and defeats the basilisks. Mars warned Frank that he could only call on the creature three times. Then the weapon would fail.  Percy and the others head to Portland, Ore., to seek the help of a seer named Phineas. They gamble with Phineas in order to get the information they need, using the two vials of gorgon blood that Frank secured back at the Roman camp. One is instant death, and one has healing powers. If Phineas wins, he’ll regain his sight, and Percy will die. But if Phineas loses, the harpies he’s tormenting go free, and he dies. He’ll also give them the location of Alcyoneus so Percy and his friends can find him. Percy wins the gamble. He, Frank, Hazel and their new harpy friend Ella set off for the Hubbard Glacier in Alaska.  Along the way, they stop in Seattle to speak to Hylla, the queen of the Amazons. In the Amazon warehouse, Hazel spies a fantastic horse from her childhood. The Amazons tell her that the horse named Arion is not for sale and can only be ridden by the greatest warrior. Then Percy and Frank are taken prisoner. After seeing Percy’s ring, Hylla agrees to speak with Hazel. Hylla reveals that Otrera, a deceased queen who has returned from the dead, is challenging her position. Hylla must battle Otrera to the death every night, but as death’s gates are open, Otrera returns to life after her defeat. After seeing that Arion has accepted Hazel as his rider, Hylla gives Hazel an escape plan and promises to help the Roman camp in their upcoming battle, if she can survive the threat to her throne. Hazel frees her friends and they ride away on Arion, the fastest horse in the world.  Arion takes the friends to Frank’s grandmother’s house in Canada. It is under siege by cannibalistic giants. Frank uses Mars’ spear to call the skeletal warrior to help them gain entrance to the house. Frank finds Grandmother dying, and his father is attending her bedside. Mars explains that Frank is one of the demigods mentioned in the prophecy. Mars also hopes that Frank has discovered how to use his family’s gift, but Frank has no clue what that could be. Mars warns Frank that his grandmother will die soon, but Frank must remember that the sweetest lives are ones that overcome difficulties. When Frank wakes in the morning, Grandmother is alert enough for one final conversation. She helps Frank to realize his family’s gift is the ability to shape shift into different animals.  Frank helps Hazel and Percy set up battle stations in the attic. He holds off the giants by shooting potatoes at them, which causes their disintegration, while Percy and Hazel go to the garage and drive Grandmother’s Cadillac outside. The giants destroy the house, but Percy and his friends escape to an airfield where a plane has been chartered to take them to Alaska. The harpy Ella won’t ride on the plane, so she takes refuge in the forest.  On the plane, Frank reveals to his friends some of what Mars told him. He also tells them about the stick of wood he gave Hazel to carry. When that wood burns completely, Frank will die. He explains that he and Percy are distantly related, as one of Frank’s ancestors was a son of Neptune as well. Percy tells the others that since drinking the gorgon blood, his memory has been returning. He knows he was part of a Greek demigod camp and that Hera sent him to bridge the animosity between the Greeks and Romans. If the Prophecy of the Seven is to be successful, they must work together.  Once in Alaska, the three demigods take a train to the Hubbard Glacier but are attacked by gryphons along the way. Frank uses the last charge of his spear to raise the skeletal warrior so it can save the other passengers while he and his friends escape. Percy then falls into a bog, but Hazel jumps in to save him. She is tempted by Gaea to betray her friends, but resists Gaea’s offer. She learns that Gaea has taken her brother, Nico, prisoner.  Hazel saves Percy, and the three continue their quest. When gryphons attack them again, Hazel makes what she thinks is a futile attempt to call Arion, whom they’d left in Canada. Arion arrives in time to save the demigods, and then carries them across the water to the Hubbard Glacier. They find Thanatos, the god of death, chained and guarded by a ghostly army. The only way to free him is to use the flames from the stick of wood that is tied to Frank’s life.  Percy takes on the ghostly army while Frank works to free Thanatos. Hazel must battle the giant Alcyoneus. Only an ember of his life stick remains when Thanatos is finally freed. In the heat of the moment, Frank is able to turn into an eagle and peck at Alcyoneus’ eyes. He then becomes a bear to take down the giant. Turning back into a human, Frank ties one end of a rope around Alcyoneus’ leg and the other end to Arion. Meanwhile, Percy has used his powers to create a tidal wave to destroy the ghostly army. Unfortunately, it takes him under as well.  Thanatos tells Hazel that he has no orders to take her back to the Underworld, so she is free to continue living. Frank and Hazel drag Alcyoneus to Canada, where he is no longer invincible. Together, they are able to defeat the giant. They return to the glacier to find Percy still alive.  The friends have succeeded in their quest. They return to the Roman camp in time to help Reyna and the rest of the demigods defeat Gaea’s army. The following day, a flying ship arrives from Camp Half-blood, the home of the Greek demigods. Knowing that Annabeth is on board, Percy convinces the Romans not to attack it, but to listen what the crew has to say.

### The Mark of Athena

Annabeth, a demigod and daughter of Athena, is both excited and nervous to be flying in the Argo II, a Greek warship designed and flown by her new friend, Leo, the son of Hephaestus. Along with Jason and Piper — also demigods — and Coach Hedge, a satyr, Annabeth hopes the Roman demigods they’re meeting won’t kill them. But Annabeth is also excited because she knows that her boyfriend, Percy Jackson, the son of Neptune, is also in the Roman camp.  At first, all goes relatively well. Annabeth and Percy are reunited, and the crew of the Argo II is treated to a Roman banquet. The Greek and Roman demigods speak civilly for the first time in centuries, explaining the quests and trials both camps have had in the past year. Their quests center around Gaea, an ancient earth goddess of immense power, who is reawakening and hoping to destroy the gods and the humans.  The demigods are sure that the Prophecy of the Seven is coming true. In it, seven demigods from Roman and Greek camps must travel to the Doors of Death and fight a battle. Percy had been warned that they must first travel to Rome to find answers before they seek the Doors.  Gaea’s allies have captured the Doors of Death and now release ancient foes from Tartarus back onto the earth to try and stop the demigods. A harpy named Ella arrives and repeats another prophecy. This one tells how the Mark of Athena burns in Rome and that twins will kill the angel of death.  Reyna, the head of the Roman camp, talks with Annabeth to learn more about the Greek demigods. Reyna tells her that she’s heard lines from Ella’s prophecy before, spoken by a son of Athena who was half-crazed from a failed quest. Reyna begins to tell Annabeth what she believes is the source of the animosity between the Greek and Roman demigods, but then explosions ring out across the camp. The Argo II is attacking the Romans.  Before the ship can be blown from the sky, Annabeth and her crew, along with Percy and his friend Frank, manage to get aboard and fly away. Hazel, another Roman demigod, follows them on her horse, Arion. After a scan from Festus, the brains of the Argo II, they decide to land near Salt Lake City to get the parts they need to repair the ship. Leo admits that he fired on the Roman camp but can’t explain why. It was as if his actions weren’t his own.  When the ship lands, Leo lets Hazel aboard. She acts like she’s met him before, although Leo is sure they never have. The demigods split up to find supplies. Frank, Percy and Annabeth go to get tar. Hazel and Leo ride Arion and find the source of celestial bronze in the area. Along the way, Hazel asks Leo if his name is really Sammy. She says he looks so much like a boy she once knew with that name.  Leo assures her that he’s always been Leo. Before they locate the celestial bronze, they run into Nemesis, the goddess of revenge. She warns them that the gods of Olympus are being pulled between their Roman and Greek natures, making them rather schizophrenic. She tells Hazel that her brother, Nico, is being kept prisoner and will die in six days unless Hazel and her friends free him.  Nemesis gives Leo a fortune cookie. Inside is the answer to a problem he won’t be able to solve. The answer, however, will require a great sacrifice. Nemesis directs them over a hill to the source of celestial bronze. It turns out to be a bronze mirror in the lake. The only problem is that it’s Narcissus’ mirror, and he won’t let them take it because once it’s removed, he won’t be able to see his reflection. After an elaborate ruse, Leo and Hazel manage to steal the mirror and return to the Argo II.  Back at the ship, Piper is worried about Jason. The Romans had knocked him unconscious before they boarded. She is also afraid of the visions she sees in her charmed knife. One of them shows the Romans rallying to find the Argo II and stop the quest. Another shows Piper, Percy and Jason drowning in a circular room.  Jason finally wakes up as the other demigods return from their errands. Leo quickly repairs the ship, and they set off for Topeka, as Piper had seen the destination in her knife, along with the god Bacchus. Once they land, Percy, Piper and Jason set off to find the god. Percy calls his Pegasus, Blackjack, while Jason calls Tempest, a wind horse. Piper rides with Jason.  When they meet with Bacchus, he gives them information about the twin giants they must face to free Nico. He also says he won’t help fight the giants unless he is given a proper tribute. Before he leaves, he tells the demigods to go to Atlanta and find Phorcys, the twins’ brother. He might be able to help them.  Gaea’s voice rises from the fields around them. Jason and Percy are possessed by eidolons, evil spirits, and are ordered to fight to the death. Jason is knocked unconscious again, but before Percy can kill him, Piper gets Blackjack to knock him out as well. She brings the boys back to the ship where they are given ambrosia, a healing liquid. They reveal what they learned from Bacchus.  Piper realizes the eidolons are still on the ship. When she asks them to reveal themselves, Jason, Percy and Leo all raise their hands. Using her charmspeak, a powerful ability to persuade others to do what she wants, Piper gets the eidolons to leave the ship and promise never to possess another member of the crew again.  In the morning, Percy tells the others about a dream he had of the twin giants. They kept Nico in a large, sealed urn. He had five seeds with him. Hazel explains that these seeds deaden the body’s systems so it can survive without food, water and little oxygen, one day at a time. The demigods land in Atlanta.  Percy, Hedge and Frank look for Phorcys at the aquarium. An employee named Kate leads them through a special entrance, explaining that they are VIPs. The demigods suspect she is some kind of monster, but follow her anyway. She takes them into an area hidden from the rest of the tourists. Mythical sea creatures are kept drugged and captive in tanks. Phorcys arrives and explains how he and his sister Keto (Kate) were exiled to Atlanta after supporting the Titans in an ancient war.  Phorcys babbles about Gaea’s plan to kill a group of demigods. All but two must be destroyed. A boy and girl must be saved to be offered as a sacrifice in order for Gaea to attain her full power. He also lets it slip that there is a map in Charleston that could help them in Rome. Then he imprisons Percy and Frank in an enchanted tank. They manage to escape with Coach Hedge’s help. They flee to the Argo II, pursued by sea monsters. Leo gets the ship in the air, and they travel to Charleston.  Once in South Carolina, Frank, Leo and Jason seek the map in an old museum, while Piper, Annabeth and Hazel seek it by the harbor. There they meet Aphrodite, who offers them tea. She explains that the ancient rift between Romans and Greeks came when the Romans stole the statue of Athena that stood in the Parthenon. They split Athena’s personality when they took the god, changing her into Minerva — the goddess of wisdom and crafts — and Bellona — the goddess of war. Athena never forgave the Romans, and throughout the centuries, has sent her children to try to find the statue and restore it to Greece. Annabeth must seek it when they arrive in Rome.  They are interrupted by the arrival of Roman legionnaires. Annabeth throws her knife into the harbor, which alerts Percy to their trouble. He causes a tidal wave to overpower the Romans. They must then save Frank and Leo, who have been shot down over Fort Sumter. The Romans have an army ready for battle, and they are surrounding the fort.  Reyna finds Annabeth and begs her to return to the Roman camp for a trial. If she doesn’t, the entire force of the Roman army will go up against Camp Half-blood. Annabeth convinces Reyna to let the seven demigods try to complete their quest. Annabeth and her friends manage to escape, and Leo sails the Argo II out to the ocean, where the Romans are afraid to follow.  Hazel shows Leo one of her memories so he can see why he reminds her of her old boyfriend Sammy. The memory shifts to show an old man Hazel doesn’t recognize. Eventually they realize that the man is Sammy and that Leo is his great-grandson. Sammy asks baby Leo to help Hazel if he ever sees her.  Before they can process what they’ve seen, a giant shrimp-like creature attacks the ship. Leo, Frank and Hazel are swept overboard and taken prisoner by fish centaurs. Once convinced they aren’t enemies, the centaurs help the demigods. The demigods promise to free the sea creatures held captive by Phorcys.  The Argo II arrives in the Mediterranean Sea, but before they can continue to Rome, Piper and Jason must face Hercules, who guards the way. He demands they retrieve the remaining horn of the river god, Achelous. If they fail to bring him the horn by sundown, Hercules will kill them.  The demigods find Achelous. Piper tricks Achelous into believing she will become his wife so he’ll let Jason go free. Jason calls down lightning to electrify the river and destroy the god. Piper manages to take his horn before he dissolves into the water. They refuse to give the horn to Hercules, instead burying him under an avalanche of food that comes from the horn, which is a cornucopia.  Once back on the boat, they are attacked by Chrysaor, another son of Poseidon, and his army of dolphin-men. Once again, the demigods are able to use deception to defeat their enemy. This time, Percy convinces the dolphin-men that Bacchus, their mortal enemy, has pledged his help to their quest. The dolphin-men flee in terror.  Frank transforms into a giant bear and attacks Chrysaor, forcing him off the boat. The demigods then fill Chrysaor’s ship with Diet Coke and sink it as an offering to Bacchus, along with the $6 million of gold and gems aboard.  Once in Rome, the demigods must split up to pursue their different quests. Annabeth seeks to follow the Mark of Athena to her mother’s statue. She eventually finds the cavern of Mithras. The spirits who guard it threaten that she may never leave. Annabeth uses her wits to keep herself alive and manages to escape by collapsing the cavern ceiling. She breaks her ankle in the process and must accomplish the rest of her quest in excruciating pain.  Frank, Leo and Hazel search Rome for any sign of Nico, Hazel’s brother. They end up in secret tunnels under the Pantheon, an ancient temple. Leo is thrilled to discover the spheres and scrolls of Archimedes, another son of Hephaestus and a brilliant engineer. Before they can leave with their treasures, they are attacked by the eidolons. The spirits take possession of the various machines Archimedes had created and attack Frank and Hazel.  Leo manages to lock himself into an area away from the creatures, but knows he must help his friends. He manages to reassemble one of Archimedes’ spheres and uses the special fortune cookie that Nemesis gave him in order to find the code to make it start, even though he knows it will mean he has to make a great sacrifice. He gets the code and uses the sphere to control the other machines. He eventually manages to make the eidolons destroy each other.  Back on the boat, Jason, Piper and Percy decide to strike out in search of Nico. They are led to an ancient silo, a shrine to the nymphs. The grotto has long been abandoned, and the nymphs have been turned to Gaea’s side. They start to fill the silo with poisonous water, drowning the demigods as both Piper and Percy have seen in their dreams. As they reach the ceiling, Piper takes out the cornucopia and orders Percy and Jason to think the best thoughts they can. They must sacrifice all their power into the cornucopia. Clean water begins to pour from it, but it still drowns the trio. With her last breath, Piper tells Jason that she loves him.  The water overwhelms them, but then, suddenly, starts to flood out of the grotto. Piper’s plan worked. The nymphs have been returned to their former selves as a result of the demigods’ willingness to sacrifice their power. Once free of the grotto, the demigods continue their search for the giants who hold Nico prisoner.  The trio finds and battles the giants, managing to briefly destroy them and set Nico free. Giants, however, cannot be destroyed without a god’s help. Bacchus arrives, but demands that Jason and Percy fight the giants in the coliseum. They do, but can’t fully defeat them until the Argo II brings an explosion. Then Bacchus delivers the deathblow to each giant.  Percy, Piper and Jason climb aboard the ship and discover Leo, Hazel and Frank have also managed to return. They set off in search of Annabeth, who is locked in a battle of wits with her mother’s mortal enemy, a giant spider named Arachne. The statue of Athena is suspended by spider silk over a chasm.  Annabeth uses deception, promising Arachne that she’ll get her tapestries displayed at Mount Olympus, but first the spider will have to create one additional masterpiece. Annabeth tricks the creature into building a huge model of Chinese handcuffs, then convinces Arachne to look inside for a flaw in the weaving. The spider gets stuck, and Annabeth is free.  The Argo II blasts through the ceiling to rescue her. Arachne falls through the chasm to Tartarus. Leo hauls the statue up into the ship. Percy helps Annabeth to her feet. Suddenly she is dragged toward the chasm because a piece of Arachne’s silk has attached to her leg.  They call for help, but their friends can’t hear them. Percy swears he will not let Annabeth go again. He and Annabeth plummet to Tartarus. Leo is convinced that this is the sacrifice he had to make for the code in the fortune cookie. The remaining demigods rally themselves to continue the quest to find the Doors of Death. It is the only way they can save their friends Annabeth and Percy.

### The House of Hades

Hazel Levasque wishes the Argo II, a boat that can both fly and float, was taking her back to her home at Camp Jupiter. But the camp, a training facility for Roman demigods, such as Hazel, is the last place she and her friends will be going. Instead, they are flying over the Apennine Mountains and being attacked by boulders thrown by mountain gods.  Hazel and five other demigods — Leo, Jason, Frank, Piper and Nico — must find a way to the House of Hades. Buried within this temple, the Doors of Death need to be found so they can rescue their friends Percy and Annabeth from Tartarus. Hazel is thrilled when her horse, Arion, appears below. The horse, which is capable of such high speeds that it can run over water, seems to want to speak with Hazel, so she climbs down the ship’s rope ladder.  Arion wants to take her into a distant funnel cloud. She agrees, knowing he wouldn’t do anything to purposely hurt her. Inside the cloud, Hazel meets with Hecate, the goddess of magic. Hecate informs her of a pass through the mountains, which the Argo II might be able to use. She also tells Hazel that she must learn to control the Mist — a supernatural veil that separates the real world from the world of myth. Hazel must develop her talent in order to save the quest when it reaches the House of Hades.  Annabeth and Percy, Greek demigods, survive in Tartarus by drinking from the Phlegethon, a river of fire. The flames burn but eventually heal them of the injuries they’ve received. Annabeth and Percy know they must make it to the Doors of Death if they’re ever going to get out of Tartarus, though they don’t know where to find them. The good news is that they spy others heading toward the Doors. The bad news is that the others are vampires they fought and killed several years ago. Percy and Annabeth follow the vampires from a distance. The vampires discover the demigods and attack. Fortunately, Bob, a Titan whose memory Percy had erased years ago, protects them. The vampires are defeated, and Bob offers to help them through Tartarus.  Back on the Argo II, dwarves sneak aboard and steal Leo’s prized Archimedes sphere. Leo and Jason track the dwarves to Bologna and retrieve the sphere. In exchange for their lives, the dwarves give them an astrolabe and a strange book the dwarves admit belongs to a minor god in Venice. The dwarves also promise to harass the Roman army of demigods marching on Camp Half-blood.  Hazel, her boyfriend, Frank, and her half-brother Nico, take the book Leo found to Venice. The city is crowded with mythical cow creatures. The creatures believe that the demigods are trying to hide their food, so they attack. Their weapon is the emission of a noxious green gas that incapacitates Hazel. Frank shape shifts into a lion and defeats several of the creatures while Nico uses his iron sword to fight them.  Frank and Nico manage to carry Hazel to Triptolemus, a god of agriculture. He turns Nico into a pot of corn and then orders Frank to get him a new python for his chariot before he will consider healing Hazel. Frank must battle with all the katobleps, the giant, poisonous cow-creatures, in order to fulfill his quest. Filled with the power of his father, Mars, Frank singlehandedly slaughters hundreds of the beasts. The battle transforms Frank physically, growing taller and more muscular. As a reward for his bravery, Mars turns one of the corpses into a python that Frank brings to Triptolemus.  Triptolemus heals Hazel and transforms Nico back to himself. He warns them that at the House of Hades they will have to drink from a chalice of poison in order to proceed to the next level of death. The only way to survive the poison is to first eat some barley.  Annabeth tries to send a message to her friends at Camp Half-blood, using the altar at the Hermes shrine. She then asks the oracle Rachel to visit Reyna, the praetor of the Roman demigods. In the note, Annabeth gives Reyna a quest that she hopes will stop the coming war between the Greek and Roman demigods.  Annabeth, Percy and Bob flee the shrine, hoping to escape the Titans who seek them. After picking up a new friend, a kitten that Bob names “Small Bob,” they encounter the aria — the curses. When they wound Percy, he is struck by a fate he gave one of his previous attackers. They also reveal Percy’s deceit to Bob. Bob is reluctant to help Percy further until he remembers that Nico visited him in Hades and told him to trust Percy. As Percy succumbs to death by gorgon’s blood, Bob defeats the curses and rescues him. But the poison remains in Percy’s blood.  Jason has a vision in which Rachel, the oracle from Camp Half-blood, meets with Reyna and several other Roman leaders. Rachel gives Reyna Annabeth’s note from Tartarus. The note asks Reyna to find the Argo II and help the crew return the revered statue of Athena within the ship to Camp Half-blood. In this way, war between the Greek and Roman demigods might be averted.  Jason and Nico visit Diocletian’s palace in Croatia in order to gain a staff that can raise an army of the dead. They will need this ghostly army to help them battle to the Doors of Death. Unfortunately for Nico, the scepter is under the protection of Cupid, the god of love. In order to get the scepter, Nico must admit whom he truly loves: Percy Jackson. Jason tries to convince his friend that neither he nor the other demigods will judge him for his feelings, but Nico is still afraid. Cupid gives the boys the scepter, and they return to the Argo II.  Bob brings Percy and Annabeth to the home of Damasen, a giant doomed to live in Tartarus, and kill a drakon (a snake-like, wingless dragon) every day for eternity. The giant heals Percy from the gorgon’s poison and allows the demigods some much-needed protection while they rest. Annabeth begs the giant to come on the quest with them so that he may return to the land of the living, but Damasen refuses.  Khione, the snow goddess, and her two half-brothers attack the Argo II. Khione has joined forces with Gaea, the mother-earth goddess, who is intent on destroying the world. Khione throws Leo overboard because of his ability to light fires. She then freezes the crew of the Argo II, except for Piper. She has promised Piper to her brother Zethes. Before she can be taken prisoner, Piper charm speaks to Festus, the mechanical dragon whose head makes up the masthead. She is able to reawaken the dragon, which then spits out fire, melting Zethes and his brother. Piper, with the power of love inside her, manages to send Khione to the underworld by stabbing her with her dagger, but not before the goddess’ wind bomb blows the Argo II dramatically off course. The ship crashes into the ground.  Percy and Annabeth trick the goddess of misery into concealing them within her Death Mist so they can travel undetected to the Doors of Death. Unfortunately, the mist also slowly kills them. They manage to escape misery’s attempt to poison them, and then evade the goddess of the dark. They jump into a gateway that leads them to the Mansion of Night, cross Acheron, the river of pain, and reach the heart of Tartarus. They know the Doors of Death are there, somewhere.  Leo manages to slow his plummet to earth by using his Archimedes Sphere. Unfortunately, it breaks from the stress. Leo crashes on an island inhabited by the sorceress Calypso. Although at first annoyed at his arrival, she soon gives him food and new clothes. Leo finds himself falling in love with the beautiful sorceress. The two work together to build a ship that will get Leo off the island, but Calypso must remain. Leo promises to return to her, but she doesn’t believe him. Other heroes have promised the same thing, only to abandon her. The encounter with Calypso changes Leo, making him less spastic and more introspective. Leo reunites with the others from the Argo II on the island of Malta, and they set off to find the Doors of Death. The Doors exist in both Tartarus and the mortal world, and the demigods must be there if Percy and Annabeth manage to free the Doors from Tartarus.  Bob leads his friends to the Doors of Death, but his Titan brothers guard them. Bob explains that even if Percy and Annabeth manage to cut the chains Gaea put on the doors and enter the elevator to return to the mortal world, someone must stay in Tartarus and hold the “up” button for 12 minutes. If the button is not pushed for the entire time, the passengers will not complete the trip. Bob doesn’t tell them where they will end up. Bob volunteers to stay behind and fight the monsters that will try and stop them from returning to the mortal world. Percy secretly tries to figure out a way to put Annabeth on the elevator and stay behind to help Bob.  Unfortunately, before the chains can be broken, the god Tartarus appears to stop the demigods. Bob attacks the god while Annabeth and Percy cut the chains. Neither will get into the elevator, however, and leave the other behind. Tartarus comes near to killing Bob, but the giant Damasen saves the Titan. As the giant attacks Tartarus, Bob promises to hold the elevator button for Percy and Annabeth. Although heartbroken that this sacrifice will end in Bob’s death, Percy and Annabeth get into the elevator. They promise to remember Bob and Damasen to their children as the best Titan and the best giant that ever lived.  Leo has brought a gift back for Frank. It’s a pouch made of magical, inflammable material. Frank can put the remaining piece of his life stick in the pouch for safekeeping. Frank has been told that once the stick burns completely, his life will end. Since then, he’s been paranoid of fire. He is touched by Leo’s thoughtfulness. The demigods find the House of Hades and consume the barley cakes they made following Triptolemus’ suggestion. Hazel leads them through the ruins until they come to the chalice of poison Triptolemus also warned them about. The barley antidote works, and the demigods proceed to the next level of death’s house.  Farther down, the demigods are separated when the floor crumbles beneath them. Hazel and Leo must forge ahead, while Frank, Nico, Piper and Jason fight the monsters released from the Doors of Death. Nico uses Diocletian’s scepter to raise an army of ghosts, but the specters won’t follow his orders because he’s not a Roman officer. The ghosts won’t follow Jason either, even though he is a Roman demigod, because they sense he’s become too Greek during his time at Camp Half-blood.  Jason promotes Frank to praetor and commander of the legion. The spirits follow his command and defend the demigods from the monsters’ attacks. Hazel and Leo battle Pasiphaë, a sorceress, and a giant named Clytius. Pasiphaë informs them that Percy and Annabeth are on their way up in the Doors of Death, but that Clytius will destroy them as soon as they arrive. The sorceress then recreates the Labyrinth, a maze in which those inside are confronted with deadly peril at every turn. Hazel understands that the maze is actually a deadly illusion, and she summons her new powers over The Mist to change the maze and defeat Pasiphaë.  The Doors of Death appear. When the doors open, Percy and Annabeth spill out, unconscious. Hazel, with the help of the goddess Hecate, manages to keep Clytius from killing them. Frank and the other demigods arrive in time to defeat the giant. Once he is dead, Hecate warns that they must speed their way to Athens to prevent Gaea’s army from destroying the world.  The demigods return to the Argo II to find Reyna waiting for them. She must return the statue of Athena to Camp Half-blood quickly, but can’t take the ship as the others must sail on to Athens. Nico offers to shadow travel with the Roman leader. Although exhausting, he feels if they travel short distances at a time, he can get Reyna back to America before the Greek and Roman demigods break out into war. The others agree to the plan. Nico and Reyna leave with the statue, while Percy and the other demigods sail on to face the oldest of the gods, Gaea.

### The Blood of Olympus

Jason, Piper and Annabeth are teenage demigods with one mortal parent and one parent of mythological, divine origin. They are in Ithaca, Greece, to investigate the sudden gathering of Penelope’s suitors, who are evil spirits (characters from Homer’s Odyssey).  The evil spirits serve the dormant earth goddess Gaea, who wants to rise from sleep and overthrow the gods and demigods. Gaea’s other evil servants, the giants, intend to bring Gaea back to life at the Acropolis in Athens. Jason tries to infiltrate the ghostly suitors, but his identity is revealed when his mother’s ghost finds him.  Jason’s mother’s ghost has become a mania, a spirit of insanity. She asks him to join her in serving Gaea, but Jason chooses to remain loyal to his friends. In an ensuing fight with the ghostly suitors, Jason defeats most of them, but is wounded. Jason calls on the Roman goddess Juno to heal him, but she is only able to offer him advice; he and his six friends should take their boat, the Argo II, to Olympia and defeat the victory goddess Nike before they go to Athens to stop the giants from raising Gaea.  From a different point of view, demigods Reyna and Nico and their satyr mentor, Coach Hedge, are transporting the 40-foot-tall Athena Parthenos statue. The statue is a valuable relic stolen from the Greek demigods at Camp Half-Blood by the Roman demigods at Camp Jupiter. Since the statue’s disappearance, the Greek and Roman demigods have been on the verge of war. The gods themselves have been split between their Greek and Roman personalities, unable to maintain a solid form or help the demigods.  Nico is a son of the Greek death god Hades and can teleport himself and others through shadow-travel, but it drains his strength. Nico is already exhausted from previous quests and tasks, so the three friends and the statue crash-land in Pompeii. Reyna, daughter of Roman war goddess Bellona, shares some of her strength with Nico to sustain him.  Reyna has a vision of the Roman praetor Octavian preparing a legion of Roman demigods to attack the Greeks at Camp Half-Blood. In eleven 11 days, the giants plan to awaken Gaea, and Octavian, who is in league with Gaea, plans to simultaneously attack Camp Half-Blood. Reyna needs to return the statue before that happens, to restore peace between Romans and Greeks.  Suddenly Gaea gives bodies made of dirt to the ghosts of Pompeii so they can attack Reyna, Nico and Coach Hedge. Nico uses a magic scepter to raise a zombie army of old Roman soldiers, and Reyna commands them with her special power as a Roman praetor. The zombies cannot defeat the earth-ghosts, and Nico teleports himself, his friends and the Athena statue to safety just in time.  Leo is a son of Greek god Hephaestus and the designer/engineer of the Argo II, currently carrying Percy Jackson, Annabeth, Piper, and a wounded Jason to Athens, along with demigods Frank and Hazel. They sail to Olympia and confront the victory goddess Nike, who takes Frank, Hazel, Percy and Leo into the Olympic stadium to make them fight each other to the death. They pretend to fight each other until Leo manages to trap Nike with his inventions.  The crew of the Argo II is looking for ingredients for something called the physician’s cure, which Nike said they would need in order to cheat death. One of the seven of them is prophesied to die in the upcoming conflict, so they need the physician’s cure to revive whoever needs it. They travel to various cities, gathering ingredients.  Reyna, Nico and Coach Hedge shadow-travel to San Juan, Puerto Rico, which is Reyna’s hometown. The hunters of Artemis capture them, and Reyna is taken to the headquarters of the Amazons, female warriors who are working with the Hunters. Reyna is surprised to find that her older sister, Hylla, is now the Amazon Queen. Hylla is trying to trap Gaea’s great hunter Orion, and she wants to use her little sister as bait, since Orion is tracking Reyna. Instead, Orion ambushes the Amazons, forcing Hylla and Reyna to team up and fight him.  The giant Polybotes captures Percy, but Jason kills the giant with help from Kymopoleia, the goddess of sea storms. Kymopoleia is angry that she never gets acknowledgement as a goddess, but Jason promises her that he will ensure that she and all the minor gods are honored at Camp Jupiter and Camp Half-Blood in the future.  Bryce, a scout from Octavian, comes to capture Reyna, but Nico defeats Bryce by using his underworld powers to turn Bryce into a spirit, effectively killing him. Nico goes unconscious for three days, and when he wakes up, Coach Hedge has called an army of pegasi to come carry the statue because Nico is too weak to transport it further.  The crew of the Argo II finds Asclepius, the god of healers, and asks him to mix together the physician’s cure for them. Leo knows that one of them must die in the fight with Gaea, and he is determined to sacrifice himself for his friends. Only Frank and Hazel are aware of Leo’s plan. The Argo II flies to Athens so they can fight the giants.  The pegasi fly Reyna, Nico and Coach Hedge near Camp Half-Blood and leave them and the Athena Parthenos safely on a yacht docked in the Long Island Sound. Reyna fights Orion one-on-one while her friends team up with the Roman troops who are not loyal to Octavian.  Reyna throws a knife into Orion’s chest, and the goddess Athena extends a cloak of protection over Reyna to shield her from Orion’s explosive arrows. Her mother, Bellona, grants her extra strength, and Reyna kills Orion by strangling him with her cloak.  Piper, Annabeth and Percy sneak into the tunnels under Athens to stop the giants’ ritual to raise Gaea. The giants need to spill demigod blood onto the earth in order to raise Gaea, and they capture Annabeth and Percy. Piper rushes to their rescue, but in the ensuing fight, both Annabeth and Percy bleed onto the ground, which means Gaea will rise.  Nico goes to Camp Half-Blood and leads a mission to disable the catapults that Octavian wants to use to annihilate the camp. The Greek and Roman demigods are on the verge of a bloody battle with each other when Nico sees Reyna flying to Camp Half-Blood with pegasi carrying the Athena Parthenos statue. Returning the statue restores peace between the Greeks and Romans, but Gaea has already awakened.  When the Athena Parthenos statue is returned to Camp Half-Blood, it also restores the divided gods, who can now lend their help. In Athens, Zeus and the other Greek gods appear to help Jason and his friends fight the giants. Soon, the giants are vanquished, but the gods cannot defeat Gaea because a prophecy says that only half-bloods can.  Zeus sends the Argo II sailing all the way to Camp Half-Blood. Leo then uses his metal dragon Festus to lift Gaea into the air, and Jason flies up with Piper to join the fight. Piper puts Gaea to sleep with charmspeak. Leo sends Jason and Piper to safety while he makes his metal dragon explode, simultaneously killing Gaea and sacrificing his own life.  The Roman demigods return to Camp Jupiter, and Jason remains at Camp Half-Blood, knowing that he’ll be visiting back and forth between the two camps in his new role as pontifex maximus, a priest who makes sure all the gods are honored. Nico, Jason, Piper, Percy and Annabeth stay at Camp Half-Blood wile Reyna, Frank and Hazel return to Camp Jupiter.  Leo revives from death in midair after injecting himself with the physician’s cure. He discovers that his metal dragon, Festus, is damaged from the explosion and has flown Leo all the way to Ogygia, the island of Calypso. Leo fell in love with Calypso in a previous novel and promised he would return to her one day. Calypso wants to leave the island, so Leo takes her with him, and they fly away on his metal dragon.
