About this product

The Sea of Monsters is a paperback fiction book in the Percy Jackson and the Olympians series by Rick Riordan. This middle-grade novel follows Percy Jackson as he faces new challenges at Camp Half-Blood, where magical boundaries are under threat. With help from friends Grover and Annabeth, and his giant half-brother Tyson, Percy must journey through the Bermuda Triangle—now known as the Sea of Monsters—to retrieve the Golden Fleece before the camp falls to mythological monsters. The story blends adventure, Greek mythology, and coming-of-age themes.
