Kaia, daughter of the ocean gods, is convinced that her life is a miracle. Years after escaping the underground prison where she and her siren sisters were kept, she is making the best of a bad situation. Her only goal is to stay alive and stay off the radar. Sounds simple, but life is never as such.

Nero is not done hunting her and it seems he has sent a particularly driven werewolf after her. No matter how far she runs, her hunter always seems to be one step ahead of her.
