Annabeth Chase is your average good girl, who is popular, has amazing friends, and is working hard toward acceptance into her dream school. Percy Jackson, on the other hand, seriously couldn't care less about life and is counting down the days until graduation. The senior class trip for this year is to the Caribbean to help build houses. All is well until some students decide to sneak onto a party boat, and two of them (Percy and Annabeth) are accidentally pushed off into the sea. From there, they're stranded on an island and who knows what could happen next?
