Thirteen-year-old Levi Middleworth insists he’s got a Destiny, even if half the internet’s tried to bully it out of him with a viral video. When a Hollywood executive in a trim green suit invites Levi to star on a reality TV show aboard a hi-tech pirate ship, Levi thinks his Destiny’s finally come a knockin’—a bit of fame is exactly what he needs to finally make some friends his eighth grade year. But almost as soon as they set sail, the games aboard the ship turn savage, and he and his new bud Holly must do everything they can to find themselves some Chums—little round-headed autonomous toys—since failing to do so means getting thrown to the sharks.

With the help of Levi’s long-lost television hero and a tech-savvy pirate crew, Levi has to rethink his quest for fame in an attempt to save himself, his fellow contestants, and every human being on the beach from a feeding frenzy of grisly proportions.
