Predators beware.

Sometimes natural predators need to be kept in check, and for that, there's Ryann David. Orphaned as an infant and raised by an exiled branch of the church to become a warrior for God, she and her fellow members of Venatores Daemonum have trained all their lives with only one purpose: destroy all demons in the mortal realm.

But when Ryann and her team are sent to hunt down a vampire who has killed one of their own, a new world of danger, betrayal, and conspiracy greets her. Allied with an irreverent psychic detective and the very monsters she was raised to kill, Ryann will risk everything—her life, her faith, and her heart—in pursuit of the truth as the black and white existence she knew turns a murky shade of gray.
