Poseidon has hung up his trident and retired to a beachside shack, trading godly battles for video games and junk food. Going by Jack Marin, this former king of the seas wants nothing more than to be left alone. But when mythical creatures start wreaking havoc and a mysterious forest nymph literally crashes through his roof, Jack's lazy retirement is shattered. Dragged back into the chaos of Olympian politics, he must confront old rivals, protect unlikely allies, and prove that even a washed-up god can still make waves—whether he likes it or not.
