The quest for the Golden Fleece begins.
When Percy Jackson, a 13-year-old demigod, returns back to Camp Half-Blood, he realizes that Thalia's tree is poisoned. Tantalus, the new activities director at camp, appoints Clarisse to lead the quest to find the Golden Fleece instead of Percy, but Hermes helps Percy, Annabeth, and Tyson to escape camp and hunt for the fleece and their lost friend, Grover. They meet Clarisse and journey together through the Sea of Monsters (also known as the Bermuda Triangle); however, the ship explodes, and Percy and Annabeth presume that Tyson is lost. After many obstacles, they reach the island of Polyphemus, the Cyclops who has the Golden Fleece.
