The story takes Jackson to the mythical land known as Sea of Monsters to retrieve a golden fleece that is essential to saving an ailing magical tree that protects his home, Camp Half-Blood. He departs with his Olympian sidekicks Annabeth Chase (daughter of the goddess Athena, played by Alexandra Daddario) and Jackson’s protective goat-like satyr Grover (Brandon T. Jackson).
New characters come along on the adventure, including Clarisse La Rue (daughter of war god Ares, played by Leven Rambin), and Tyson the Cyclops (Douglas Smith), who, to Jackson’s dismay, is revealed to be his half-brother. Turns out Tyson was also fathered by Poseidon, this time with a sea nymph mother.
“Those Greek gods really got around,” says Freudenthal. “They were kind of dysfunctional partying drunkards: living first, thinking later.”
Two of those gods make their series debut in Sea of Monsters: the messenger god Hermes (Nathan Fillion) and Dionysus, the god of wine (Stanley Tucci).
The daunting foes include a myriad of monsters, from the football-field-sized sea creature Charybdis to the Manticore, which Freudenthal describes as a half-lion, half-scorpion that wreaks “considerable harm.” Jackson’s final battle takes place with Kronos, the overlord of the gods and the central villain in the book series.
