Vayne is a light elemental and bounty hunter for the supernatural world. Her partners—Giovanni, a capricious fallen angel; and Donovan, a shape shifter with anger control issues—work with her during their rehabilitation. During the coldest winter Cincinnati has ever seen, the threesome run into a case where temporary and violent insanity strikes powerful elementals seemingly at random. Vayne soon finds herself the victim instead of the hunter, and working on the wrong side of the conflict. How can Don and Gio pull her back from the brink? How will she reveal the perpetrator and bring him before the chopping block?
