"A publisher in New York asked me to write down what I know about the Greek gods, and I was like, Can we do this anonymously? Because I don't need the Olympians mad at me again. But if it helps you to know your Greek gods, and survive an encounter with them if they ever show up in your face, then I guess writing all this down will be my good deed for the week. So begins Percy Jackson's Greek Gods, in which the son of Poseidon adds his own magic--and...

"Greek and Roman demigods from the Prophecy of Seven must work together to seal the Doors of Death--and help Percy and Annabeth escape the Underworld in the process"--

Based on the publishing phenomenon, Percy Jackson and other young demigods continue to fight, but this time in the sea, to fulfill their destinies. To save their world, Percy and his friends must find the fabled and magical Golden Fleece. Embarking on a treacherous odyssey into the uncharted waters of the Sea of Monsters (known to humans as the Bermuda Triangle), they battle terrifying creatures, an army of zombies, and the ultimate Evil.

After learning that the father he never knew is Poseidon, God of the Sea, Percy Jackson is transferred from boarding school to Camp Half-Blood, a summer camp for demigods, and becomes involved in a quest to prevent a catastrophic war between the gods.
