Percy Jackson

Perseus "Percy" Jackson is a seventeen-year-old Greek demigod, the son of Poseidon and Sally Jackson. He is the main protagonist and narrator of the *Percy Jackson and the Olympians* series, and one of the main characters of *The Heroes of Olympus* series. He is the head counselor at Poseidon's Cabin and a former Praetor of the Twelfth Legion at Camp Jupiter, formerly belonging to the legion’s Fifth Cohort. He was the temporary host of the Egyptian goddess Nekhbet. Percy is currently the boyfriend of Annabeth Chase.

***Percy Jackson and the Olympians*
---------------------------------****### *The Lightning Thief***Percy learned that the director of the camp was the Greek wine god, Dionysus, who was very unpleasant and moody, and Mr. Brunner, the former Latin teacher from Yancy Academy, was actually the hero-training centaur (half-human, half stallion), Chiron. Shown around camp by Annabeth, his new friend and head counselor of 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. 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 dethrone him because he 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. Soon after learning that Master Bolt has been stolen, Percy embarks a quest with his sword Anaklusmos, better known as Riptide, 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 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 (which Ares gave him) 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.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 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.

Then, Artemis and her Hunters appear and Annabeth falls from a cliff as she had climbed on Dr. Thorn with her knife before the Hunters shot him down with their arrows. Being a son of Poseidon, Percy did not feel Annabeth dropping into the water, which confirms the fact that she had been captured. The Hunters saved Percy and his friends from the manticore. After a while, Percy clearly understood that he and Thalia were not under speaking terms due to the fact that Annabeth had fallen down the cliff. Nico had taken a great interest in the fact that he was a demigod and exchanged many thoughts on the Greek gods, while Bianca had been dumbfounded and was summoned by Artemis with Percy, where Bianca pledged her life to Artemis much to Percy's protests to become a Hunter (unaware at the time that she was a daughter of Hades and by joining the Hunters, she removed herself as a possible subject of the Great Prophecy).
Artemis then sends her Hunters to Camp Half-Blood with Apollo, her twin brother. When he got to camp, Percy had frequent dreams about Annabeth and that she was in distress. He even went to see the Oracle of Delphi, however, she didn't answer his questions and he left the attic in anger.
After a few days, the camp had a Capture the Flag game, where the Hunters were up against the campers. Thalia and Percy agreed to be co-captains of the demigod team while Zoë Nightshade leads the Hunters. During the game, he learned from Grover that Zoë had a bad dream about Artemis being in trouble, while Percy himself had a dream that Annabeth was suffering under the weight of some unseen object (later revealed to be the sky). Thalia told Percy to stay on defense to guard the flag, but when he saw that her team was about to be attacked, he ran up the middle and took the flag. On his way back, he saw Zoë running back with his team's flag and was tripped up by an arrow two feet from the line, allowing the Hunters to win.

Thalia then runs up to Percy, asking him what he was thinking as when she got to the flag's spot, it was gone. She then shocks him with Electrokinesis but claims it was an accident and apologizes. Percy, angry uses the creek water to splash her and claims that it was also an accident. Thalia and Percy begin to fight, each one summoning stronger attacks until Percy stopped, seeing the Oracle walking towards them. Percy simply watched as the Oracle approached Zoë, who asked about saving Artemis. The Oracle replied with a prophecy, saying:
*Five shall go west to the goddess in chains,*
*One shall be lost in the land without rain,*
*The bane of Olympus shows the trail,*
*Campers and Hunters combined prevail,*
*The Titan's curse must one withstand,*
*And one shall perish by a parent's hand*

Chiron then holds a meeting to decide who will go on the quest. Zoë originally wanted to take all Hunters, but she is convinced to allow a few campers as it was in the prophecy. Zoë, however, doesn't pick Percy because he is a boy, as Zoe thinks it's horrible to be with a boy, instead of picking Thalia and Grover, as well as her own Hunters, Bianca di Angelo, and Phoebe. Percy was mad that he was not allowed to take part in the quest since it was his chance to save Annabeth. That night, he is awoken by Blackjack, a pegasus who tells him a sea creature is in trouble. He swims out and finds the sea cow trapped in a net and frees it slowly because it was scared of his sword, forcing him to free it by hand. On his way back to camp, he sees Nico spying on the Artemis' Cabin and uses Annabeth's cap to follow him. Percy overheard Zoe telling Bianca that Phoebe had been poisoned by centaur blood on a shirt that Connor and Travis Stoll had given her earlier as revenge for her defeating them during Capture The Flag so she couldn't go. Revealing himself to Nico, he is forced to promise Nico that he will watch out for his sister after Nico correctly guesses that Percy will follow the group on their quest. Nico leaves and Percy had just enough time to turn invisible before the Hunters leave the cabin, with Zoë almost bumping into Percy on her way out. As they leave, Percy followed them from above on his pegasi, Blackjack. They followed the car that the four traveled in and stops hours later when the group arrives at the Air and Space Museum in Washington, D.C. Percy then spots Dr. Thorn, the manticore, and overhears him saying that Annabeth is alive and that his dreams were true. He follows the manticore when it doesn't follow the group into the museum. He soon finds the General (Atlas) and Luke and sees the General creating several Spartus that he was going to use to kill him and Bianca. However, the Spartus got hold of parts of Percy's sleeve instead of the General's piece of cloth with the Hunters' scent on it, resulting in them hunting him instead. Percy quickly escapes using Annabeth's Yankee cap to find the others. Zoë in particular, was surprised and angry when they realize that he had followed them and they were soon attacked by a Nemean Lion with the Spartus close behind. After finding the lion's weakness, Percy helps defeat it by filling the monster's mouth with astronaut food he found in the gift shop. This made the monster expose his mouth long enough for Zoë to finish it off with an arrow. The lion left behind a Spoil of War, its pelt, which Zoë gave to Percy as he had come up with the plan even though she dealt the finishing arrow. She also allowed him to join the quest after realizing that he is the fifth quest member, despite the fact that the Spartus, now disguised as gray security men thanks to the Mist, are tracking him. They fled Washington and made it to a train line, where they jumped into a rail car with a homeless man who offered them his fire. Though at first oblivious to the identity of the homeless land, a very bad haiku reveals him to be Apollo. He asked Percy to save his sister by looking for Nereus, the Old Man of the Sea, as he could tell them where to find Artemis. Later that night, Percy has a dream where, unbeknownst to him, he is Hercules, and is being handed Anaklusmos by a girl who he later realizes is Zoë. Apollo takes them as far west as far as he could, to the last stop in a small town in New Mexico. Despite there being no real way out of the town, they tried to think of ways to leave including renting a cab. However, the Skeleton Warriors managed to find them again and attacked with handguns while Grover passes out as Pan's presence overcomes him. As they tried to defend themselves against the undead soldiers, who would reform when killed, Grover senses Pan's presence again, along with a gift from the wild - the Erymanthian Boar. However, because it is wild it attacks everyone, not only defeating the skeleton warriors and Thalia and Percy lead it into the woods. They are cornered at a cliff and he tells Thalia to jump at the last second. Thalia, however, is scared of heights, which Percy quickly figured out and pushed her out of the way causing the boar to crash into the snow.
Grover managed to use his nature magic to make an apple appear in front of the monster's face and the group rides it to a junkyard in Gila Claw, Arizona, owned by Hephaestus. They camp there for the night, but a limo appears and Percy's blood began to boil, which meant Ares was nearby. The god of war came out of the car and told Percy to get inside, as someone wanted to talk to him. Percy reluctantly does so and finds Aphrodite inside. She asks him to hold a mirror as she fixes some microscopic flaws on her face. As Percy watches her, she seemed to change into all the girls he had ever had a crush on. Aphrodite begins to talk about tragic love stories and eventually asked Percy why he was on the quest. He originally told her it was to save Artemis, but with some pushing by the love goddess, he admits that he is really there to save Annabeth. Aphrodite thrills at his response and tells him that she will make his love life very interesting, hinting that Annabeth and Percy will most likely have a romantic future together. She then sends him back to his friends and warns him not to take anything from her husband’s junkyard.
While passing through, Bianca took a Mythomagic game piece of Hades for her brother, Nico because it was the only one that Nico didn't have. Because of this slight mistake, a defective automaton came to life and started attacking the group. Percy notices a manhole cover at the bottom of the machine's foot and was planning to enter it, however, Bianca went in instead, sacrificing herself to kill the monster and save her friends. Percy and everyone else tried saving her, but they knew that it was completely useless as Grover announces tearfully that the next line of the prophecy has been fulfilled.
Thalia takes a truck and drives them to a river, where they rent a few canoes and Percy convinces a few Naiads to steer them to the Hoover Dam. When the Naiads start messing with him and Zoë, she tells him that they have never forgiven her. When they near the dam, Percy, along with Thalia and Grover, begin sprouting facts about the Dam, indicating the depth of their relationship with Annabeth is as the Hoover Dam was one of her personal favorites. They also make *dam* jokes about the Dam Snack Bar and the Dam Restroom, though Zoë was lost on the humor. As they go to get food, Percy hears the sound of a sea creature he had befriended earlier. He tells it to go away and wonders how it followed him, but is distracted by the sight of remaining Skeleton Warriors - Bianca had managed to kill one in New Mexico.
He runs into an elevator to escape them but then becomes trapped deep inside the dam. A tour guide, who turns out to be Athena (Percy later realizes it was her since she had Annabeth's eyes and that she was trying to help him save her daughter), tells him that there is always a way out for those that are smart enough to find them, before ascending in the elevator. He is spooked when a girl appears behind him and he swings at her with Riptide, but the sword simply passes through her as she is a regular mortal. She then reveals she isn't so regular, as she sees the Skeleton Warriors for what they truly are and directs them away from Percy, who hid in a bathroom. As he thanks her, he introduces himself as Percy and that he has to go (which Rachel thinks means his name is *Percy Gotta-go*).
Up top, he warns the others of the danger and they are cornered at the top of the dam. He tells Thalia to pray to her father, but she doesn't think he will answer. He says that Athena thinks he will and Thalia asked her father for help. Two statues come to life and swat the undead skeletons away before flying the group to California. There, Zoë Nightshade, who knows a lot about Nereus, tells Percy to look for him by smell as it is *different*. Percy finds him and hangs on for dear life as the old man tried to shake him off. Percy tricks him into going into the sea, which makes Percy stronger. Nereus changes into many animals to shake Percy off, but his attempts fail and he eventually agreed to answer their question. Percy asked what the terrible monster that Artemis was hunting was, which Nereus says is easy and points to the water before escaping. Percy feels tricked until Bessie, the sea creature that had been following him, appears in the water. Grover understands it and they quickly learn it is the Ophiotaurus, the monster Artemis had been seeking as burning its entrails will give the person who does the power to destroy Olympus.
Just then, Dr. Thorn appears with a small force of mortals and attacked the group, wanting to make his own place in the Titan Army. He tried to convince Thalia to slay and burn the Ophiotaurus so that she could destroy Olympus but Percy manages to shake her out of her stupor. When they were cornered, Percy sends an Iris Message to Camp Half-Blood but finds only Dionysus on the other line. Mr. D makes Percy ask him politely for help, which Percy does between clenched teeth, and the god saves them by wrapping the manticore and his men in grapevines, saving their lives. Percy then reluctantly thanks, Dionysus. He then sacrifices the Nemean Lion's pelt to Poseidon to ensure safe passage for Grover and Bessie back to Camp Half-Blood.
Percy then goes to see Annabeth's father, Frederick Chase, as he may have a car they could use to save his daughter. After meeting Annabeth's family, he is shocked that they are so much different from the way Annabeth had described them, as to him they only seem caring and loving. Mr. Chase wants to save his daughter personally but is told it is too dangerous for him, being just a regular mortal. He reluctantly agrees and gives them his car. Before they leave, Percy makes a promise to Mrs. Chase to tell Annabeth that she still has a home there with them.
As they drive up the mountain towards the Garden of the Hesperides, the car explodes due to a lightning bolt that struck it forcing them to complete the rest of the climb on foot. When they reach the Garden, Percy and Thalia find out that Zoë is a Hesperide after meeting her sisters, and she is poisoned by the dragon, Ladon but manages to distract it clearing a path for the others. Then they continue on to the place where Atlas held up the sky, though they find Artemis holding that burden instead. Percy finds Annabeth bound and gagged by Luke and the General, who is actually Atlas. Percy challenged Atlas, but his sword becomes too heavy, as Ares curse had finally taken hold (Ares promised that his sword would fail him when he needed it most when Percy won against him before). They were thrown into battle where Luke and Thalia fight each other, while Percy tries his best to hold off Atlas. In the ensuing fight, Percy saw the ruins of Mount Othrys, rival capital of Mount Olympus and home of the Titans, rebuilding itself. He realizes that this meant that the Titans' chances of victory are increasing.
Zoë then intervenes, fighting her father, disappointed with what her father had done. Percy used that moment to ask Artemis to give him the sky as he realized that the prophecy had involved him and that only Artemis could have a chance against Atlas. He took it while Zoë and Artemis attacked Atlas together, but Zoë is hit and thrown against the wall speeding up the poisoning done by Ladon which begins to kill her. Artemis managed to push him back under the sky while Percy rolled out of the way. Sadly, Zoë began to die as Percy ran up to her during her last moments. She tells him that he is nothing like Hercules who had betrayed her before and she is proud he carries the weapon she made before dying.
Percy rescued Annabeth and they manage to escape the mountain, thanks in part to Frederick Chase shooting the monsters with his plane using Celestial Bronze bullets. He, along with Annabeth and Thalia, then go to Mount Olympus on Blackjack and his friends, Guido and Porkpie. While flying, Percy and Thalia believe that Luke is dead as Thalia had thrown him down a deep chasm, but Annabeth believes otherwise. Percy becomes slightly jealous of the affection Annabeth was showing for Luke, which surprises him because it has never really bothered him before now.
When they arrive in Mount Olympus, the winter solstice meeting had already begun, and they begged Zeus to believe that Kronos was indeed rising. Thalia then chose to be a lieutenant with Artemis to replace Zoë, before giving Percy a hug. When he said she wasn't allowed to do that anymore (as Hunters can't become attached to males), she says she was merely honoring a friend. The gods then voted if they should kill Percy as he is the only known child of the Big Three to reach sixteen for the Great Prophecy in two years. Fortunately, many of the gods vote to let him live after Artemis declares that if he is killed, then the gods are then no better than the Titans. Poseidon also vouches to let the Ophiotaurus live, although kept in Mount Olympus so it wouldn't be a "bargaining chip" against the other gods. Before Percy leaves Olympus, Poseidon tells Percy in private that he has done well and he is proud of him. Percy and Annabeth go off to resume their unfinished dance from Westover Hall.
Back at camp, Percy tells Nico that his sister had died and gives him the Mythomagic figurine of Hades that Bianca meant to give to Nico. However, Nico blames Percy for not protecting her and throws the figurine away, telling him he hates Percy. At that moment, four of the Spartus appear, somehow managing to get past the Camp Borders. Nico thinks that they are for him and unintentionally splits the earth to swallow them and send them to the Underworld before fleeing into the forest. Percy, realizing that Nico is a child of Hades after the incident, tries finding him, but to no avail. While discussing Nico's abilities with Annabeth, Grover appears, claiming that he'd heard Pan's voice in his head. The three then promise to keep it a secret as Percy knows that Nico could also be a child of the Great Prophecy, but instead says that he himself will take the responsibility of the prophecy instead.
During a game that Quintus made up, Annabeth and Percy go through the rocks of Zeus's Fist and fall in a dark cavern which they later find out is an entrance to the Labyrinth. Annabeth is offered the quest she has been waiting for since age 7: She must enter the Labyrinth, find Daedalus, and get Ariadne's String before their arch enemy, Luke Castellan does. Luke has been planning on burning down Camp Half-Blood and is trying to use the Labyrinth to get there, guided by Ariadne's String. As Annabeth goes inside to get her prophecy, Percy waited outside and felt a little worried when Annabeth didn't come back for a long time. When she returns, Annabeth begins to tell everyone what the Oracle had told her, but she doesn't say the last line saying she doesn't remember. This strikes Percy as strange that she would forget something so important and begins to wonder what the last line could be. Annabeth takes Percy, Grover, and Tyson along with her. Together, they enter the maze. They are joined by Hera for a short time. She tells them that Percy knows the way, but Percy doesn't know what she means by that. When they take a wrong turn throughout the maze they run into Nico, son of Hades, at the Triple G. Ranch. Nico is accompanied by King Minos’s ghost, who tries to convince Nico that they are not his friends. Once they get out without Nico, Percy and the others run into a quiz show run by a Sphinx.
After they escape from the Sphinx, they find an exit that takes them to Hephaestus, who has them travel to one of his forges to find out who has been using them, and in return, he will help them find Daedalus. Percy gets lost in the inner depths of Mount Saint Helens while battling fierce Telekhines. Before parting with Annabeth, she kisses him for luck. Percy faces four full-grown telekhines. They attempt to burn him with lava, but Percy, being a son of Poseidon, is hard to burn. In desperation, he unleashes an incredible amount of power and blasts out of Mt. Saint Helens, creating an explosion that damages the volcano, stirs Typhon in his sleep, and causes the evacuation of hundreds of thousands of people living around Mt. Saint Helens. He ends up falling into Ogygia, where he meets Calypso, a young girl whom Percy thinks is much prettier than Aphrodite herself. Percy must leave the island and Calypso (who has fallen in love with him) behind. Calypso lets him use a magic raft that will take him to any place he wants, and the only place he can think of is Camp Half-Blood.
He returns to the shores of the camp and finds the camp strangely empty, except the amphitheater where everyone has gathered. As it turns out, they were getting ready to burn his shroud. Annabeth took the stage to say her final words, stating "He was probably the bravest friend I've ever had. He..." She then suddenly saw him and starts hugging him fiercely until she realizes she was making a big scene in front of all of the other campers. As they talk about plans to navigate the labyrinth, Percy realized he knew the answer after talking with Hephaestus on Ogygia; they need a mortal with clear sight to guide them. Once they are accompanied by Rachel, they run into a wide arena, where Percy battles a dracaenae and the demigod Ethan Nakamura. Sparing Ethan, Percy challenges his giant half-brother, Antaeus, the arena master, that is accompanying Luke so that Luke's army can pass. Percy kills him by luring him off the ground, as his mother is Gaea meaning he is invincible on the ground.
When he finds Annabeth and Rachel again, Rachel leads them straight to Daedalus' workshop, who tells them that he is Daedalus and the name Quintus was only a cover, and he also reveals that they are too late; Luke got there first and took Ariadne's string. He says that Rachel is better and more accurate than the string. Monsters then attack the workshop, dragging in Nico in chains. Percy, Rachel, Annabeth, and Nico escape and leave Daedalus and Mrs. O'Leary to fight the remaining monsters. They find another entrance and enter the maze once again. Once they navigate through the maze, Percy hears the Titan Lord speak to him. Taking Annabeth's invisibility cap, he goes into the room and opens the coffin. There, not fully formed, is Luke. As much as Percy hated him, Percy did not draw Riptide. He finds the demigod whom he spared earlier in the maze, Ethan. Ethan joins the Titan's side and Kronos comes to life in Luke's body. Percy barely escapes, thanks to Nico and Rachel (who had hit Kronos in the eye with a blue plastic hairbrush).
While they were going through the Labyrinth, they meet up with Tyson and Grover again. Together, they all find Pan, the god of the wild, who tells them he is dying. As his spirit dies, it goes into the mouths of each of them except Nico, and it seems that Grover got a little bit more than the rest. Rachel leads them to New York, where pegasi take Percy, Annabeth, Grover, Nico and reluctantly, Tyson. The five of them had to leave Rachel behind because she is fully human. They go to help the camp ready for the Titan army's arrival. Battling side by side is Annabeth and Percy. Percy and Annabeth fight Kampê along with Briares's help. Grover, in a panic, screams so loudly that it scares the Titan army back into the Labyrinth. Grover's dryad girlfriend, Juniper, insists that it was Pan's wild scream that had scared the Titan army the first time. As Percy gets up, Daedalus comes and tells them that the Labyrinth is tied to his life. The child of Athena (Daedalus) dies, and so does the Labyrinth. Percy, Annabeth, and the other uninjured campers take the wounded to the Big House.
Percy decides to leave camp and go celebrate his birthday with his mom. Two surprising visitors stop by while Percy, Tyson, his mom, and Paul Blofis (Percy's mom's new boyfriend and fiancée) are celebrating. First, Percy's father Poseidon comes and tells him that he fears Luke/Kronos is only temporarily defeated and when Percy blew up Mt. Saint Helens, Typhon stirred in his sleep. Finally departing with Poseidon, Percy decides to go to his room to plant the garden he had earlier promised Calypso. As he does, Nico stops by and tells him that he needs to tell Percy things about how they might be able to stop the Titan army. Percy then invites him for cake and ice cream.
In the water, he drifts to Poseidon's palace under the sea where he meets Tyson and other relatives. Poseidon is fighting Oceanus and his army, aging rapidly due to the state of his kingdom being destroyed. Percy wants to stay and fight, but he must return to Camp Half-Blood to relay news of what happened on *Princess Andromeda* to the campers. Chiron and Annabeth agree to show him the Great Prophecy, and after reading it he learns that his fate is to make an important choice and to have his soul reaped by a cursed blade. Percy is all keyed up for a while afterward until a confrontation with Annabeth when she calls him out as a coward. As he contemplates his fate, Nico returns to discuss the secret plan introduced in *The Battle of the Labyrinth*. He wants Percy to bathe in the River Styx to become invulnerable like the hero Achilles. To do so, Percy Jackson must first discover how Luke could do it and they go visit his mother, May Castellan in Connecticut, where they find her insane and unstable. She does tell them that Luke came and asked her for her blessing for something that he needed to do. They also meet the goddess of the hearth, Hestia, who shows Percy visions of the destruction being caused by Typhon. Percy and Nico visit Sally and Paul back in the city, to get her blessing. She insists that Percy is now his own person and that she has to let him go. Nico leads Percy to the Underworld, where Hades reveals that it was all a trick to make Nico the child of the prophecy. Nico rescues Percy, though he seems to have lost his trust, and takes him to the Styx, where he is submerged in the water and becomes invulnerable, but for one tiny spot on his lower back.
The war begins and Percy leads the group of demigods into a dormant Manhattan to battle monsters and demons, while the gods are battling the monstrous Typhon in the east. Rachel arrives, revealing that she has had a vision that read, "Perseus, you are not the hero. It will affect what you do." Ethan, who was aiming at Percy's Achilles Spot during a battle to invade New York City nearly killed Percy but Annabeth had pushed herself in the way as if she had a feeling that Percy was in danger so she got injured instead. Percy is furious and horrified, knocking Ethan unconscious with his sword. Kronos threatens Percy to surrender or he will kill Annabeth, but Percy calls Blackjack who takes her to a hotel in a plaza. Annabeth is seriously injured, and Percy tells her where his Achilles spot is and that she saved his life. Annabeth remarks he looks "cute when worried" and that his eyebrows "get all scrunched up." When Kronos makes it to the Hall of the Gods, Percy battles him to stop the destruction of the Olympians' Thrones, which, if destroyed will cause the Olympians to lose their power. Kronos asks Ethan to kill Percy as he knows where his Achilles' spot is, however, Percy convinces him that what he is doing is wrong. Ethan then attacks Kronos and strikes him on the shoulder with his blade. However, due to Kronos also bearing the Curse of Achilles, Ethan's blade cracks and he harms himself fatally. Kronos then opens up a fissure which causes Ethan to fall to his death for his betrayal. Annabeth is able to convince Luke to resurface. She reminds him of his promise that he would protect her and asks Percy to give him the knife so that he can defeat Kronos. Percy hands over the knife, discovering he was not the hero after all, but his choice to give it to Luke was the decision he had to make, and it decided by fate of Olympus. Kronos is blown to dust and scattered by the wind, and Luke dies a hero's death. Right after that, the gods arrived after successfully defeating Typhon and are shocked to see Luke's dead body on the ground.
Through deaths and betrayals, the demigods stand victorious. Percy is offered the gift of becoming a god, but declines due to his feelings for Annabeth. He remembers how he felt when Annabeth might have become a Hunter of Artemis and notices Annabeth looks about the same way that he did then. Because of this, he declines their offer in favor of a request. He requests that the gods claim their children by the age of thirteen and that Camp Half-Blood construct cabins for Hades and the minor gods so their children have a place at camp. When he comes back to Camp Half-Blood, he finally expresses his feelings for Annabeth and they kiss twice, the first time in Camp Half-Blood's mess hall, and the second time being underwater, due to which a group of eavesdroppers tosses them into the lake, the latter which he describes as 'pretty much the best underwater kiss of all time.' At the very end of the book, he and Annabeth share a moment of bliss as they race toward the road down Half-Blood Hill back into the mortal world, not looking back at Camp Half-Blood for once.
