The Percy Jackson and the Olympians3: The Titan's Curse 波西傑克森3:泰坦魔咒

A quest is issued and the group is made to go on a quest for Artemis. However, Percy is not part of that quest. Grover, Thalia, Bianca and Zoë Nightshade, Artemis's lieutenant, go to rescue Artemis. Percy secretly follows and soon joins the quest as the fifth member. They travel to various places such as the Hoover Dam and the junkyard of the gods. In the junkyard, Percy is visited by the goddess of beauty and love, Aphrodite, who tells Percy that she is quite interested in Percy and Annabeth's romantic tension that is shown discreetly within the books, but becomes more pronounced throughout the series. They learn that Atlas, a powerful Titan, has escaped his torment (holding up the sky) at the Mountain of Despair on California's Mount Tamalpais, replacing himself with Annabeth and then eventually Artemis, and is intent on stopping the heroes from success. They defeat him, having lost both Hunters in the quest. At the winter solstice, Thalia replaces Zoë as Artemis' lieutenant at a meeting with the gods in which they decide whether they would kill Percy and his friends. Thalia had escaped the prophecy, leaving Perseus alone in it. Fortunately, Percy and his friends remain untouched. The gods, Percy, Annabeth, Grover and Thalia, then celebrate the victory of defeating Atlas and everything else the heroes accomplished. But as soon as they return, Nico is told about Bianca's death. He blames Percy, accusing him of failing to protect her like he had promised. When a crack in the ground appears, and the dead come out, Nico thinks that Percy is now trying to kill him as well. He tells them to leave and they are banished to the Underworld; Nico then runs away. Percy realizes that Hades is Nico's father. At first, Percy, Annabeth and Grover think that this goes against the promise of the Big Three, which is to never have demigod children, but they realize the two siblings had been in the Lotus Hotel and Casino (visited in the first book where time is nonexistent, and you lose complete track of time), before the pact between the Big Three was ever made. But Nico is still a part of the prophecy, so Percy has to hide Nico's parentage, in case Luke tries to recruit him so Nico can destroy the world at the age of 16.
