A Hero's Nightmare Becomes Reality

Percy Jackson's summer begins with recurring nightmares about his friend Grover in danger. These aren't ordinary dreams-they're demigod visions warning of real peril. On his last day of seventh grade (a miracle for a kid who usually gets expelled), Percy learns that Camp Half-Blood, his summer sanctuary for demigods like himself, faces mysterious "problems." Before he can learn more, disaster strikes during a dodgeball game when his classmates transform into eight-foot Laistrygonian cannibals hurling explosive bronze balls. In the chaos, Percy's only school friend Tyson reveals surprising strength and immunity to fire. Then Annabeth Chase-Percy's friend from camp-appears from nowhere to help them escape. As they flee in the Gray Sisters Taxi (driven by three bickering blind women sharing a single eye), Percy discovers something terrible has happened at Camp Half-Blood. Arriving at camp, they find the unthinkable-the magical boundary protecting the demigods has weakened, allowing monsters to attack. The cause? Thalia's pine tree, which creates the protective barrier, has been poisoned. Even worse, Chiron has been fired and replaced by Tantalus, a cruel spirit from the Fields of Punishment who shows particular animosity toward Percy. When Percy proposes a quest to find the Golden Fleece that could heal the tree, Tantalus assigns Percy's rival Clarisse instead. That night, the god Hermes appears on the beach, offering magical gifts to help Percy undertake the quest regardless of permission-because he hopes Percy might save not just Grover but also Luke, Hermes' traitorous son who has aligned himself with the titan lord Kronos.
