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.
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.
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.
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.
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.
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.
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.
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.

Like the other books in the series, "The Titan's Curse" is of the fantasy genre. It uses the ancient Greek mythology in a modern setting as background. Reviewers have called its plot "fast-paced", meaning that the story moves very quickly. It has humor as well as themes such as love and loyalty.
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.
