Bo had no reason to believe she was different to her human parents – until she finds she is a Succubus, one of the legendary Fae, who drain their victims of sexual energy. She hits the road, alone and afraid and finds that she is not alone. Relieved yet still horrified at what she and her kind are, she chooses a middle path between humans and Fae, helping both with the aid of her human friend Kenzi and Dyson, a Fae posing as a human detective and at the same time, making it her mission to discover her own origins.
