Grover is undercover once again, this time at a military school, where he discovers two children, Nico and Bianca di Angelo, that he suspects are half-bloods. In the excitement of his discovery, Grover asks Percy to come and help him safely bring the half-bloods to camp half-blood. In the process of trying to get to the di Angelos, a manticore (Dr. Thorn) attempts kidnaps Percy, Bianca, and Nico, only to lose them to Thalia, Annabeth, and Grover. As they battle Dr. Thorn, the Hunters of Artemis step in and rid of the monster by making him trip off a cliff, which led to the loss of Annabeth, her being on Thorn's back. Artemis leaves her Hunters to be escorted to Camp Half-Blood by Percy, Grover, and Thalia. Artemis is then kidnapped, which means that a quest must be launched to save her. That quest consists of Grover, Bianca (who is a new Hunter of Artemis), Zoe Nightshade (The chief Hunter of Artemis), Thalia, and Percy, who journey across the country to Mt. Tampalais
. Tampalais. On the way, Grover is involved in several situations where Pan, god of the Wild, speaks to him. The first was in Cloudcroft, New Mexico, where the presence of Pan made the birds on Grover's coffee cup and a rubber rat come to life, also bringing a giant wild boar to help Percy, Thalia, him, Bianca and Zoe escape the skeletal army. The second incident happened when Grover was alone. Pan spoke to him, saying, "I await you." Both times, Grover was drinking coffee, so he and the other satyrs believe, that this had something to do with Pan's appearance.
The Battle of the Labyrinth

It is in this book that we meet Juniper, Grover's nymph girlfriend, who is sobbing hysterically as The Council of Cloven Elders' decide that Grover has been searching far too long for the god Pan — they give him a week to find Pan, and if he does not, his searcher's license will be revoked. He, Percy, Annabeth and Tyson head into the Labyrinth this time to find its creator, Daedalus, and his workshop. Sometime in the book, Grover and Tyson split up from Percy and Annabeth. However, Grover meets a monster. Later, Grover finds Pan and learns the truth about his disappearance and that he, the God of Wild Things, must fade away and leave the job of making the earth green again to Grover, Annabeth, Percy, Tyson and everyone else on the planet. Grover unleashes the cry of Panic, greatly disrupting the Battle, and distracting the enemy long enough for the campers to surge and eventually drive them back into the Labyrinth.

The Last Olympian

Grover has been missing for 2 months; Percy and Nico decide to look for him on their way to the Underworld. Percy locates Grover through his empathy link in Central Park and finds him under a giant elm tree. Percy wakes him up by yelling, (via empathy link) "FOOD, PANCAKES!". He tells them he just took a nap and they figure out that Morpheus, the god of dreams, put Grover to sleep. In that way, Grover gives Percy and Nico info that some minor gods are on Kronos' side. He helps Nico and Percy get into the Underworld by playing his reed pipes to open up an entrance in Central Park.

After, his exile is ended and he is given a position in the Council of Cloven Elders. Grover is then appointed as the new Lord of the Wild, causing him to collapse with joy on the spot.

The right whales (Eubalaena spp.), also known as the black whales are baleen whales with bow-shaped lower jaw and a head that is up to one-quarter of the body length. The head is hairier than most whales; up to 300 hairs are found on the tip of the lower jaw and 100 are on the upper jaw. There are also callosities (a series of horny growths) behind the blowhole, on the chin, above the eyes, on the lower lip, and on the rostrum (the beak-like upper jaw).

Description 
Right whales are similar to bowhead whales, but smaller. These whales are rich in blubber and have 2 blowholes. The eyes are very small and lips are large. Right whales were named by whalers who considered them the "right" whales to hunt, since they were rich in blubber, they were easy to catch (they are relatively slow swimmers) and they floated after being killed.
History 
Hunters needed the right whale's blubber for meat, because blubber could be boiled to make oil.
The right whale's name came from hunters, who thought that they were the "right" whales to hunt. This was because they had lots of blubber. They were also easy to catch (because they were relatively slow swimmers) and they floated on the surface of the water after being killed. Because of these things, right whales are the most endangered of the great whales.

Writers from San Antonio, Texas
Luke Castellan is one of the main antagonists (being a traitor) in Rick Riordan's Percy Jackson & The Olympians series. He is a demigod son of the Greek god Hermes.

Luke is played by Jake Abel in the movies Percy Jackson & the Olympians: The Lightning Thief, the film adaption of the first book, The Lightning Thief and Percy Jackson: Sea of Monsters, the film adaption of the second book The Sea of Monsters.
Character background
Luke is first introduced in The Lightning Thief as the 19-year-old counselor for the Hermes cabin. He was born the year 1986. While the rest of Percy's cabin mates complain about him because he is undetermined, Luke tries to make him feel at home, even stealing a toiletry bag for him. Luke first came to Camp Half-Blood when he was 14, alongside Thalia Grace, daughter of Zeus, and Annabeth Chase, daughter of Athena. Luke has a scar on his face, a relic from his battle with the dragon Ladon, guardian of the Garden of Hesperides, while on a quest. In The Last Olympian, it is shown that his mother attempted to become the Oracle of Delphi and has succumbed to the curse of Hades. Her crazed prophetic ramblings affected Luke greatly, and forced him to run away when he was nine. In The Battle of the Labyrinth, Luke's body becomes the vessel that harbors Kronos' essence.
Luke dies in The Last Olympian when he is given Annabeth's knife by Percy. He sacrifices himself to defeat Kronos by stabbing himself under his left arm where his mortality was still kept intact after his bath in the River Styx (known as his Achilles heel). As he dies, he asks Percy to make sure all the demigods are claimed to avoid this happening again which might mean that they had become friends again because he is forgiven by Percy. Although he is seen as a villain throughout the series, in the end he is treated like a hero and forgiven by everyone. He is also the hero mentioned by the prophecy of the Oracle in The Last Olympian.
Power/abilities
 Luke has ADHD like other half-bloods, which allows him a heightened awareness in combat.
 As with most other half-bloods, Luke is dyslexic because his brain has been "hard-wired" to read Ancient Greek.
 Luke is said to be an amazing fighter and swordsman, "The best swordsman in 300 years", as mentioned by a Hermes camper in The Lightning Thief, although Thalia Grace, his old friend, can always beat him in battle.
 He has the Curse of Achilles, which gives him near invincibility except in one part of his body (in this case, beneath his left arm).
 His soul is fused with Kronos', giving him Kronos' abilities.
 Being a child of Hermes, Luke has abilities that involve traveling and theft. He has displayed such powers twice. In The Lightning Thief, he slashes through the air and disappears through the ripple he created. In The Titan's Curse, he conjures up a pool of water and a sacrificial fire by waving his hand.
Strong willpower, as evidenced by his ability to host Kronos in his body without completely losing his identity.
He also can use powers to break locks and open doors
Weapons/magical items
Backbiter – a blade with one side of celestial bronze melded with tempered steel. The celestial bronze allows for the wounding of immortals and monsters, while the steel injures mortal. Backbiter is a foot longer than Anaklusmos, Percy's sword. Percy sensed a tragedy in the making of Backbiter. In the fourth book, it is revealed that the metal used for Backbiter came from Kronos's scythe. It is reforged into its original form for its master's rising.
 A pair of magical sneakers that can sprout wings when the owner says, "Maia", the name of Luke's paternal grandmother. The sneakers were given to him by his father Hermes and bear a close resemblance to Hermes's own winged shoes. In The Lightning Thief, Luke cursed them into pulling the wearer of shoes into the pits of Tartarus; however, since Grover put them on instead of Percy it confused the curse. The shoes are now gone, for they slipped off of Grover and fell into Tartarus.
Kronos's Scythe – when Kronos is brought back to life in Luke's form, the telekhines gave him Kronos's scythe, which is reforged out of Backbiter. No amount of celestial bronze can beat it.

Percy Jackson and the Olympians characters
Rachel Elizabeth Dare is a red haired fictional character in Rick Riordan's Percy Jackson & the Olympians stories. Unlike other big characters in the series, none of her parents are gods. Instead, they both are mortal. Despite this, Rachel has the ability to see through Mist, a thing that makes most humans unaware of the Olympians and immortals. She has the power to predict things, which is not common even with demigods. Because of these powers, the Oracle of Delphi passes into her from the cursed remains of the previous oracle. She therefore becomes the next Oracle of Delphi, Oracle of the Gods as well as the resident oracle at Camp Half-Blood. By becoming the Oracle, she gives up her romance with Percy because the Oracle must be a maiden.

Background

The Titan's Curse
The Titan's Curse

In this book, Rachel first appears at the Hoover Dam (in which they have a dam problem). Percy is being chased by a group of Spartoi when she sneezes. Percy turns around and his sword, Riptide, goes through her body. He realizes she knows it is a sword. He also finds out that she can see through the Mist. She saves Percy from the Spartoi by sending him into a restroom behind her and the skeletons to the generator room, which makes electricity.

The Battle of the Labyrinth
In The Battle of the Labyrinth, more details on Rachel's life are given. She shows up at Percy's new school, Goode High School. She can see that two cheerleaders are really empousai and helps Percy escape from Kelli, one of the empousai. Later, Percy asks her to help him navigate Daedalus's Labyrinth, a maze he built, to find him. She goes with Percy and Annabeth through the maze. After finding out Daedalus has made a deal with Kronos, she escapes with Percy and Annabeth. Eventually, the three find Kronos's headquarters. Kronos has started to live in Luke Castellan's body and tries to catch Percy. Rachel appears with Annabeth and Nico di Angelo and throws her blue plastic hairbrush at Luke's eye. This confuses Kronos and lets Percy escape. She also helps find Pan, the lost god of nature. She is there when he dies.
Later, she leaves Percy, Annabeth, Nico, Grover Underwood, and Tyson. Before she does, she tells them that her father is a rich businessman who buys forests. He cuts them down and use them to build shopping malls. Pan's death affects her, mainly because of her father's job. She wants to hang out with Percy again. Annabeth is not happy about this. Percy promises to call her. He says that he has memorized her phone number. Rachel is happy about this. Percy thinks of inviting her to his birthday party. He is too afraid to do so.

Rachel and Percy become good friends in The Battle of the Labyrinth. Annabeth becomes jealous of her. Rachel also sees that Percy and Annabeth like each other more than they will admit.

The Last Olympian
The Last Olympian

The Last Olympian begins with Percy driving her to the beach in Paul Blofis's Toyota Prius. She asks him to go with her and her parents on a vacation in St. Thomas, which he refuses nicely. They are interrupted by Percy's pegasus, Blackjack. He lands on the car with Charles Beckendorf riding him.
Percy goes to sink the Princess Andromeda, a ship which Kronos is using as his base. Rachel kisses him for good luck before he leaves. In Percy's dreams, he sees Rachel writing things in Ancient Greek. She is drawing pictures of things she has never seen before, like a picture of Luke Castellan at age nine. When she goes on vacation with her parents, she asks them to return to New York by making a deal with her father to go Clarion Academy. Clarion Academy is a finishing school (a girls' school that teaches culture and social things) for girls that her mother also went to. This was all because she felt that Percy was in danger. Later on, Rachel flies to Camp Half-Blood on Blackjack. She takes in the spirit of the Oracle because Hades lifts the curse he had put on it. She says the next Great Prophecy. Rachel then goes back to the mortal world for the school year, leaving the campers without their oracle until the next summer.
Personality
Rachel's father is extremely wealthy, but she does not like the way her familly lives. She prefers helping charity. She also likes art, and sketched multiple realistic images of the past and future (sometimes things she never could have seen, like a 9-year-old Luke Castellan).

Rachel is a love interest for Percy, which created tension between her and Annabeth. However, she explains that she was attracted to Percy because he was the one who led her to her destiny as the Oracle. As the Oracle, she cannot fall in love or have children. She has respect for Annabeth and Percy's relationship.

Powers and abilities
She can see through the Mist, an unusual ability for most mortals.
She became the Oracle, allowing her to see the future.
She can navigate through the Labyrinth.

Percy Jackson and the Olympians characters
Nico di Angelo, is a fictional character in Rick Riordan's Percy Jackson & The Olympians, The Heroes of Olympus series and The Trials of Apollo. In the series, he is the demigod son of Hades and mortal Maria di Angelo. As such, Nico has extraordinary powers of necromancy, the power to command the dead and the power to summon the dead. He is a son of one of the "Big Three" Greek gods, the other two being Hades' brothers Poseidon and Zeus. Nico is chronologically over eighty years old as a result of his prolonged stay in the Lotus Casino in Las Vegas, an enchanted hotel where one does not age and time does not pass at its normal pace. He was ten years old in The Titan's Curse. He and his sister, Bianca di Angelo, were placed in the Lotus Casino sometime around World War II. They were eventually taken out by a "lawyer" (The Fury, Alecto) when Hades commanded. He also found his half-sister Hazel Levesque in the Underworld and took her back to Camp Jupiter as she was a child of Pluto.
Description
Nico is said to have shaggy, messy black hair, olive skin (although it has paled over time) and dark brown eyes. After his time in the maze, he is described as having a pale complexion. He usually wears dark clothing including black ripped jeans and is also mentioned on several occasions to be wearing an aviator's jacket. By the end of The Battle of the Labyrinth, he also wears a skull ring, a gift from his deceased sister Bianca.
In The Titan's Curse, Nico is a composed kid who loves a trading card game called Mythomagic. However, since his sister's death in The Titan's Curse at the hands of a defective Talos, he has a hateful resentment toward Percy. He later thinks Mythomagic is a stupid game, and burns all his cards in a fire. He becomes more sullen and solitary, saying that "only the dead respect him...and only out of fear". He believes that he will never be accepted with the living, but forgives Percy after Bianca tells him that it wasn't Percy's fault that she died. He also accepts the small figurine of Hades that Bianca wanted him to have before she died in The Titan's Curse. In the fifth book, he brings Percy to his father to get information that proves to be the least his father can give, and his father ends up putting Percy in a dungeon. However, Nico rescues Percy from the dungeon and takes him to the River Styx where Percy becomes almost invincible
. In the end of The Last Olympian, Nico convinces his father, Hades, to help the other gods fight in the war against the Lord of Time, Kronos, and his army, and plays a major role in the victory. The relationship between Percy and Nico becomes close for they both might have been the child of the Great Prophecy.
In The House of Hades, Nico is forced by Cupid to reveal that he had had a crush on Percy Jackson. This reveals that he is gay. In The Blood of Olympus, he later says that he does not feel that way anymore about Percy, and that he had been young and impressionable at the time, (by saying Percy is "not his type") and is seen to be potentially crushing on Will Solace (head counselor of the Apollo cabin).

In The Trials of Apollo: The Hidden Oracle, Nico is in a romantic relationship with Will and receives the enthusiastic support of Apollo (Will's father) for their relationship.

In the books

The Titan's Curse
Nico is ten years old and first appears with his sister, Bianca, in a military school called Westover Hall in Bar Harbor, Maine. They are sought out by Grover Underwood, the satyr, who believes them to be two very powerful unknown half-bloods. Nico seems to be very interested in Mythomagic, a game about Greek mythology. When his sister Bianca accepts Artemis's proposal to become a Hunter, Nico gets angry at her for "abandoning" him. Percy finds Nico eavesdropping on Bianca and Zöe Nightshade (one of the Hunters of Artemis, a daughter of Atlas), and Nico makes Percy to promise to keep his sister safe. He does not appear again until the end of the book, where Percy explains to him that Bianca died to save the others on the quest. Nico creates a large crack in the ground to swallow up the skeletons that were chasing Percy. The he immediately turns on Percy, telling him he hates him, and reminds him of the oath he took to keep Bianca safe
. Nico is last seen running into the woods at night, after screaming at Percy.
The Battle of The Labyrinth

Nico is supposedly eleven years old in this book. He is first seen talking with an unknown ghost who is trying to tell Nico how to trade his sister's soul for another soul, when Percy is sent a collect Iris Message sent by Bianca Di Angelo, Nico's sister. It is revealed in this book that Nico can summon the dead. Nico is then seen when Percy, Annabeth, Grover, and Tyson visit Triple G Ranch, where Percy then saves Nico from being sent to the Titans. Nico, still angry at Percy, finally understands that it was Bianca's choice to go into the Talos robot, and that he shouldn't be mad at Percy. The others leave Nico at the Ranch, where he supposedly meets King Minos (in ghost form) again, who convinces him to go back into the Labyrinth to supposedly save Percy and the others.
He is next seen being dragged into Daedalus' workshop by one empousa and two Laestrygonians, in chains, after being tricked by King Minos. He escapes with Percy, Annabeth, and Rachel Elizabeth Dare, who have to go back into the Labyrinth to find Grover and Tyson, who had stayed behind to look for Pan, god of the Wild. Along the way, they see Kronos in the form of Luke, and Nico, in a desperate attempt to save everyone, shows his true powers, and makes it known to Kronos that he is a son of Hades. They meet the wild god Pan, who gives everyone except for Nico a cryptic future reading and then vanishes. After they get out of the Labyrinth, a full-fledged battle erupts between the Titans and Camp Half-Blood, in which Nico summons a dozen undead soldiers to fight the dracanae, passing out in the process. He is revived with nectar and ambrosia, and he states that summoning that many soldiers required a lot of energy. After the campfire, he is seen talking with the ghost of his sister Bianca
. He then tells Percy, who came out to see what was going on, that he did not belong at camp, but instead in the Underworld; he would train there instead. He also goes to search for his mother. He is last seen on Percy's apartment fire escape giving Percy news on Daedalus and a way to beat Luke for good. Before mentioning it, Nico is distracted by Percy's blue birthday cake, and Percy invites him in to talk.
The Last Olympian

Nico is twelve years old in this book. His theory to gain an edge over the Titans is to make Percy invincible by having him bathe in the River Styx, similar to the myth of Achilles. It is shown that after Bianca died, Hades feels he has no competent child, repeatedly mentioning that Bianca could do a better job at fulfilling their father's demands than Nico. It is also revealed that the lawyer who removed the children from the Lotus Casino was Hades' lead Fury, Alecto, in disguise.

The Last Olympian
Nico is in about the quarter of the way in the book, he brings Percy Jackson to May Castellan's house, and Hades palace to talk with Hades but instead to Percy Jackson gets put in the dungeon and rescued by Nico. He fights but comes a little late to help with the Kronos war, at the end of the book he talks about Rachel Elizabeth Dare being missing.
The Son of Neptune 
Nico appears in the beginning of the book, He is visiting his half-sister Hazel, who was showing Percy (after losing his memory) Camp Jupiter at the time. Nico lies to Percy about knowing him after he finds out that Percy's memories have been stolen and simply says that he's an ambassador for Pluto at the Roman camp. It is later made clear that this was to preserve diplomacy (since Greeks and Romans didn't get along) and not interfere with Hera's plans - rather than a malicious urge.

The Mark of Athena 
Though Nico was inside of a bronze jar (after getting captured) during most of The Mark of Athena, he does get rescued by Piper, Jason and Percy. Nico also explains to the others where the doors of death are and how to close them. When Percy and Annabeth are holding on for dear life at the edge of a chasm that lead to Tartarus, Nico desperately tries and fails to save them before they fall into Tartarus, promising he would lead the others to the other side of the doors of death.
The House of Hades 
Nico admits his feelings for Percy when he is confronted by Cupid. This makes Nico the first demigod acknowledged as gay in the series. He indirectly shares this secret with Jason, who is with him at the time, and then is obliged to explain. Nico appears to trust Jason in this scene, even if only grudgingly. Afterwards, Nico offers to shadow travel the Athena Parthenos in an attempt to bring the Roman and Greek camps together. He is accompanied by Praetor Reyna and the satyr Coach Hedge.

The Blood of Olympus 
Nico helps transport the Athena Parthenos to Camp Half-blood to halt the attack from the Camp Jupiter. He is joined by Reyna and Coach Hedge. The trio shadow travel halfway around the world, causing Nico to lose a lot of his strength and start to "fade". When facing Bryce Lawrence, it was demonstrated that Nico could turn people into ghostly specters with enough effort.
Hades was also alluded to have been aware about Nico's romantic feelings for Percy during one of his conversations with his son. Hades gives Nico his blessing and tells him he'll prepare a room for Nico in the Underworld for if his mission should fail. He also informs Nico that he wants him to be happy, and that he is proud of his son.

Upon landing at Camp Half-Blood with Reyna and Coach Hedge he leaves them to destroy the onagers, where he finds Will Solace, Lou Ellen and Cecil. Will Solace and Nico start bickering, which amuses Lou Ellen and Cecil.
Later on, it is shown that Nico has not visited the infirmary or spoken to Will since the battle, and Will expresses his dismay at this, saying that Nico could at least have dropped by and Will would have been glad to see a friendly face. This surprises Nico, who hadn't realized Will might want to see him, and says that his face is usually not welcome, especially around the wounded/sick. Will is upset by this and protests, stating that people were always trying to befriend Nico, it was simply that Nico would not allow them to. 

Some time later, when Nico answers the door to his cabin and sees Jason Grace, he momentarily mistakes him for Will, feeling disappointed when he realizes his mistake. He then feels annoyed with himself at being disappointed, and it is implied that he is interested in Will Solace.
After a conversation later on in which Will orders Nico to stay at the infirmary for three days of rest, Nico sees Percy and Annabeth and decides to clear the air between them, since they will be seeing a lot of each other in the next few years. He confesses his old feelings for Percy, while Annabeth looks on, smiling reassuringly and even offering him a high-five for managing both to say the words and to utterly astound Percy, who was oblivious of his feelings (at the time they existed). He says that Percy is not his type, and he was simply young, confused, lonely and scared with no one else to turn to or trust at the time.  After, he walks towards a waving Will Solace, the boy he chooses. In  the Trials of Apollo we get a glimpse of their relationship. It is the first Homosexual couple in Rick's books with the ship name ‘Solangelo’.

Powers and abilities
General
Nico's sword is made of Stygian Iron, which will kill monsters, and, unlike the other metals of Celestial Bronze and Imperial Gold, is capable of harming mortals. The metal, when being forged, is cooled in the River Styx, making it indestructible. It is implied that only beings of the Underworld, such as Hades and his children, are able to use a Stygian iron weapon. The sword helps him channel his power to control and summon the dead, along with draining an enemy's soul to reinforce his sword's power. He can also use it to create fissures in the ground, trapping anyone unlucky in the underworld. This is like what he did to king Minos. Nico being an incredibly powerful demigod; he has many powers and is aware that “With great power... comes a great need to take a nap," as he says after putting to sleep all of the skeleton guards in the Palace of Hades during his and Percy's escape from imprisonment during the Last Olympian.
Nico has ADHD like other half-bloods, which allows him a heightened sense of awareness in combat.
 As with most other half-bloods, Nico is dyslexic because his brain has been "hard-wired" for Ancient Greek. However, not all are dyslexic or have ADHD, such as Frank Zhang.
 Nico, being a son of Hades, is one of the most powerful demigods alive.
 He can slay monsters with little effort.
Powers
 Nico can open up grounds and bury creatures alive.
 Nico has dominion over the dead, giving him the title ‘Ghost King’.
 Nico can summon and communicate with the dead.
 He can sense when a mortal or half-blood has died through a buzzing in his ears
 Nico is shown to be able to release a soul into the underworld, as he did with Daedalus.
 Nico can shadow-travel, a form of travel that uses shadows that enables him to teleport to different places although this ability tires him after a long period of time and he can begin to ‘fade’.
 Nico can bend shadows around him to conceal himself.
 He can control dark energy like Hades but to a much weaker extent.
 He can shadow travel others by force if he has direct skin-to-skin contact with them.
 He can cause immensely powerful tremors.
 He can control the dark obsidian souls of the underworld.
He can travel through dreams 
 He can see others memories
He can force ghosts into silence by putting a finger to his lips.
He can turn others into ghosts and send them into the underworld as he did with Bryce Lawrence.
 He can release dark waves from his body, these waves were so powerful that they almost knocked out Jason as collateral damage.

Thalia Grace is a fictional supporting character in Rick Riordan's Percy Jackson and the Olympians series, as well as a minor character in the Heroes of Olympus, as Jason's sister. She is the demigod daughter of Zeus and Beryl Grace, a famous mortal actress. Thalia has angel-blue eyes ( thought done say she has stormy green), black short spiky hair, and a spray of freckles and a brilliant singing voice.
Background
Thalia Grace is the daughter of Zeus, one of the "Big Three" Greek Gods, the other two being Poseidon and Hades. Grover Underwood was meant to watch over her when she ran away from home at ten years old, reaching Camp Half-Blood two years later. On her journey, she met Annabeth Chase and Luke Castellan. They had brief encounters with the Hunters of Artemis, and were almost convinced to join, but got angry with Zoe Nightshade and did not join. When she was twelve, they were all attacked by a herd of monsters and caught by a Cyclops in New York. She was captured, but thanks to Annabeth, freed. They ran, but the monsters they had briefly escaped from caught up to them. As they reached Half-Blood Hill, Thalia sent Luke, Grover, and Annabeth over the boundary line while she faced the monsters. She sacrificed her life for her friends, but her father Zeus took pity on her and turned her into a pine tree to preserve her, keeping the rest of the camp safe.
Thalia is a very skilled fighter and as she stated in The Titan's Curse; she can always beat Luke in a battle (which Percy has only done once). It is also mentioned throughout the series that she has a punk sort of style, hates Barbie dolls, and likes Green Day. She is always listening to rock bands and is into the punk subculture. Annabeth compares her to Percy, telling him, "You guys are so alike it's scary. Either you would have been best friends, or you would have strangled each other."

Thalia wants to be strong as many people believe, but sometimes is very sensitive. She loves Chiron as a father and believes that her father does not care about her. She deeply respects Poseidon but does not know why. Her favorite god is Pan. She is also known to like cheeseburgers, mentioned twice in the series. She also appears reluctant to use her mother's surname.

Percy Jackson and the Olympians

The Lightning Thief
It is mentioned that Thalia was turned into a pine tree when she risked her life saving her friends atop of Half-Blood Hill, which guarded the boundary line for Camp Half-Blood. She also appeared in Percy's dream. This is one of the first movies that came from the series, in fact it is the first movie. However, she was mentioned a few times, no one in the beginning really knew why.

The Sea of Monsters
Thalia appears in Percy's dreams throughout the book. At the end of The Sea of Monsters, she is brought back to life by the Golden Fleece which Clarisse places on her pine tree. Zeus gives her a spear which shoots electricity and turns into a small mace canister that fits in her pocket, and Athena gives her a bracelet that turns into Aegis, a shield with the Medusa's head carved into it. It is a replica of her father’s. Thalia is now potentially the child of the prophecy, and Kronos soon takes advantage of the fact. in the sea of monsters Percy uses the sea as a compass to navigate to find the golden sheet which will bring back Thalia as her tree was dying in front of the camp

The Titan's Curse
Thalia and Percy quarrel occasionally at camp because their similar personalities tend to clash. Thalia is called "Pinecone Face" by Percy; in retaliation, she calls him "Seaweed Brain", which Percy does not like because it's Annabeth's pet name for him. Thalia goes on the quest to find Artemis, hunt down the dangerous Ophiotaurus Artemis was seeking, and rescue Annabeth, along with Percy, Zoë Nightshade, Bianca di Angelo, and Grover. Thalia, Percy, Zoe, Bianca, and Grover come upon the Junkyard of the Gods and told not to take anything from the junkyard, and just as the group is about to leave, a metal giant rises because Bianca took a figurine of her father, Hades, for Nico. Bianca goes inside of the metal giant and tries to control it, causing the giant to fall over and Bianca to die. Together, they face the Titan General, Atlas's army, and make it to Mount Tamalpais. Already weakened by dragon poison, while facing her father, Atlas, Zoe dies from a final blow from Atlas
. There, Thalia fights her old friend Luke, and it seems that she has strong feelings for him, and they discover that Kronos used Thalia to twist destiny into her hands, since she would be turning sixteen on the day following the Winter Solstice. She escaped this deadly path and turned to her half-sister, Artemis, who made her a Hunter, which would stop her from being sixteen, because whoever becomes a Hunter becomes immortal, unless they shall die in battle, or break the oath by falling in love.
Thalia's tree still remains standing on Half-Blood Hill with the Golden Fleece for energy, and is currently being guarded by a baby dragon called Peleus.

The Battle of the Labyrinth 

Thalia is absent from Camp Half-Blood this summer due to her adventures with Artemis and the Hunters, but she is mentioned once by Percy when talking to Hera, the goddess of marriage, about Zeus and Ms. Grace's past relationship.

The Last Olympian

Thalia and the Hunters of Artemis show up when Percy is looking for someone to defend the Lincoln Tunnel against the Titans. Thalia helps Percy and the other demigods defend Manhattan. At the end of the story, Thalia is still alive, and is granted help in getting more Hunters, because a lot of the Hunters died.

The Heroes of Olympus

The Lost Hero 

Thalia shows up at the cave by Aeolus' palace, along with the other hunters. She also fights at the wolf house when the hunters help Leo, Jason, and Piper fight the monsters and the giant.
The Son of Neptune 
There are two parts in which she is either mentioned or appeared. First, in Percy's dream which was a flashback of him in The Titan's Curse, Thalia, Percy and Zoë Nightshade battling on Mt. Tam going against Atlas, Luke, and trying to save Annabeth and Artemis. Percy later sees Zoë dying and rise to the stars. Second, though Thalia was never mentioned, when Hylla, the Queen of the Amazons, talks to Hazel Levesque she mentions a group of archers that travel around who follow the goddess Artemis, which refers to the Hunters.
The Blood of Olympus 
Thalia and the hunters abducted Reyna Avila Ramírez-Arellano in San Juan and took her to her sister Hylla Ramírez-Arellano. She explained that the hunters and Amazons have been fighting monsters while the demigods have been fighting each other. Orion then attacked their stronghold, killing many Hunters and Amazons though Thalia and Hylla manage to survive. When Nico and Hedge appear, she protects them while they and Reyna shadow travel away. She survives the battle.

The Trials of Apollo

The Dark Prophecy 
Thalia and the hunters were close by when Apollo signaled for back up. They arrived with Leo and Festus to aid in the rescue operation and she decided to rode on Livia with Apollo, so she could help them to escape. After they fled, the lieutenant of Artemis offered the fallen god Moonwater to regain his strength. Then she finally says Artemis was forbidden by Zeus from interfering with Apollo but still ordered the Hunters to help him. They three then head back to the Waystation.
She and Apollo ride Livia in to the Waystation and she goes to stop her hunters from possibly killing Lityerses. After they rally everyone for battle she requests more arrows from Emmie.

Halfway through the battle, she along with Lit, Calypso and Josephine stood by as Commodus had Emmie, Leo and Georgie hostage. Apollo asks her to stand down before he goes not his Divine Form and blinds the emperor. She takes out one of his guards and searched the surrounding area for Commodus with no results. After that, she sits with everybody and discuss about the prophecy revealed by Meg, saying that the Hunters can't help because they just have one mission to finish.

Before she and the Hunters leave, she asks Apollo to say hello to Jason and Piper. In return, the god asks her to say hi to Artemis for him, which she agrees to do.
Fatal flaw
It is implied that she has a weak resistance when she is offered power. She is also afraid of heights, a quality Percy finds strange, as her father is the Lord of the Sky. She is also extremely determined, as revealed in the short story The Sword of Hades in The Demigod Files. She has trouble abandoning a difficult task that she has started but is not able to complete.

Powers and abilities

Natural abilities
 Thalia has ADHD like other half-bloods, which allows her heightened awareness in combat.
 As with all other half-bloods, Thalia is dyslexic because her brain has been "hard-wired" for Ancient Greek.
 Thalia becomes one of Artemis's hunters in the end of The Titan's Curse, and as a result, is immortal unless she dies in battle or breaks her oath to Artemis, which is to foreswear romantic love forever.
 Thalia can 'manipulate the Mist", which means she can make things as she wants them to appear to the eyes of a mortal (taught to her by Chiron).
 Thalia is a good fighter, able to beat Luke.
Zeus-relative powers
 Thalia, as the daughter of Zeus, is more powerful than most demigods and on a par in strength with Percy and Nico because they are also children of the Big Three.
 Thalia can send powerful amounts of static shock throughout another's body on contact.
 Things that belong to her father's domain can do as she asks, such as statues of the angels in The Titan's Curse, which were gifts to her father. They, on her request, flew her and her friends to San Francisco.
 Thalia has a strong leadership quality which is probably a result of being the daughter of Zeus.
 Thalia can also manipulate electricity and lightning because Zeus, the god of lightning, is her father.
 Thalia has some control over air and the sky, being daughter of Zeus, Lord of the Sky. Since she has acrophobia, or fear of heights, she has yet to test them.
Weapons
 A copy of Aegis that expands from a metal bracelet that she wears on her wrist, which many of the campers and monsters cower in front of
 A collapsible spear that expands from a Mace canister
 A Hunter's bow
 Two hunting knives

Plot summary
Plot summary

Annabeth Chase and Artemis, the goddess of the hunt, are kidnapped and Percy and his friends must find Artemis before the winter solstice. This is because at the winter solstice, her influence on the Olympian Council could change an important vote. The vote was on the war with the Titans. Thalia Grace, Zoë Nightshade, Bianca Di Angelo, and Grover go on this dangerous quest. They also are searching for a rare monster that Artemis was trying to hunt down when she went missing. This monster is so powerful that it can destroy Olympus. Percy is called by a hippocampus (which is a mythological sea-horse) to rescue a cow-like creature called the Ophiotaurus which lives in the sea. Percy names the Ophiotaurus "Bessie". He did not know that it is a male.
In San Francisco, they learn that Bessie the Ophiotaurus is the monster Artemis was searching. This is because sacrificing it and burning its entrails will give a person the power to destroy Olympus. They ask for the help of Annabeth's father who gives them a car. They travel to the Garden of Hesperides, where Zoë meets her sisters. She is poisoned by a dragon called Ladon. They continue to the Mountain of Despair on California's Mount Tamalpais, where Mt. Othrys, the Titan capital, is now present. From the top of the mountain where Atlas held up the sky, they see Artemis holding the sky. Annabeth is held captive by Luke. Percy takes the burden—the Titan's curse—from Artemis. After this, a fight breaks out. Atlas (the General of the Titans) kills his daughter Zoë by throwing her against rocks. Artemis tricks Atlas into taking his burden from Percy. Luke falls from a cliff during a battle with Thalia, and Percy thinks that he is dead
. They go to Olympus and they keep Ophiotaurus there and at that party Percy is told by Annabeth that Luke has survived.
