Madison Fox is determined to reform Jamie, her half-evil pooka, but the bond linking her to Jamie works both ways. Already, it has manipulated her into bending the rules. If she continues down this path, she could doom her soul. Since her judgment can't be trusted, a high-ranking inspector now dictates Madison's every interaction with Jamie, and each directive drives them further apart. Unfortunately, Madison has bigger issues than the potential degradation of her soul.
Winter has struck with a vengeance. Frost moths plague the entire state, reinforcing the artificially frigid temperature. Worse, cold-blooded, soul-stealing enemies are flocking into her region from the north-creatures Madison has little defense against.
With the inspector scrutinizing her every misstep, Madison is in for the battle of her life. If she hopes to survive, she must make an impossible choice: Save herself and her region, or save Jamie.
