Tawne Delaney is not what men consider beautiful and, at 37, is very lonely. She fantasizes about her dream lover--but the man she meets is a nightmare. Arcan Tyler is a rapist and murderer, possessed by animal spirit forces. If they are unleashed, he will cease to be human. For now, Arcan is all too human, and finds something new and rare in Tawne. But love among these creatures is not romantic: it is parasitic.
