A human stranger crashes into a world of fur and fangs, hunted by undead ships and a priest's iron grip. William, a jaded doctor, teams up with Hanna Calico-a cutlass-wielding cat pirate-and her wild crew to defy gods and claw their way free. From stormy seas to a jailbreak in Mathis, chaos reigns as a cursed map points to Athena's forbidden heart. Pirates, prophecies, and a fight for survival-will they break the chains or sink in the storm?
