After the murder of a friend, teen gods and demigods join forces to face a common threat, but unexpected romantic feelings complicate their mission.

Poseidon asks Prometheus and his troop of young gods aboard the Marcella II to search for pirates and their ship, the Tarantula. But in a twist of events that even the legendary gods couldn’t see coming, the Marcella II is found first, the young gods are captured, Prometheus is beheaded, and a mortal friend is killed.

Shocked by this turn of events, Hades recruits demigods Gertie and Hector to join in the effort to rescue the young gods and uncover the secret of the vampire pirate organization. But love and duty collide, and nothing goes as expected.
