Willing to do whatever it takes to save her sister, Nerissa Elliot commandeers the ship of notorious pirate, Cyrus Crow. But Crow has a mission: kill Nerissa and earn his freedom from the Queen who's controlled him half his life. However, Nerissa harbors powers over the sea. Powers she can't control. Powers that threaten to consume her. With nothing but a tenuous facade of an alliance and sparks between them, they set sail to face sirens, sea dragons, betrayal, and Nerissa's own uncontrollable ability. Can they find the strength to trust each other? Or will they destroy one another for the sake of their quests?
