Detective Casie Blackwood thought she'd left her supernatural past behind when she joined the police force ten years ago, fleeing the shame of public mate rejection and family abandonment. Now, ritualistic murders are forcing her back into a world she desperately wanted to forget. Three human victims have been discovered with surgical precision wounds and ancient symbols carved into their palms—markings that point to forbidden blood magic from before the supernatural communities established peaceful coexistence.

Partnered with Detective Rick O'Connor, who remains unaware of her true nature, Casie must navigate the investigation while concealing her enhanced senses and knowledge of the supernatural.

As federal agents circle and media attention intensifies, Casie must choose between maintaining her carefully constructed human life and embracing the supernatural heritage she rejected.
