Imogen Crim has been terribly bored since she returned to Blandington. So when her nemesis-turned-best friend Ava Kruk offers to swing by the Crims' dreadful beach vacation in Dullport and rescue her in her stolen submarine, Imogen quickly agrees. A real heist with a real villain--this is the excitement Imogen has been looking for. But before Imogen and Ava can accomplish their mission, the entire Crim family catches up to them, dressed in their pirate-y finest. And what starts as an innocent (well, for a boat full of criminals) quest for buried treasure is about to become a stand-off with an up-and-coming super villain called The Gull. If Imogen has any hope of saving her family from his claws--and returning to her vacation--she'll have to trust a Kruk with her life.
