Roger is a detective, but unlike other detectives, his cases deal with the supernatural. If fighting monsters and demons weren't enough, he has to put up with the split personality of his partner—a sexy and seductive succubus called Voluptia. She also happens to be madly in love with him. Unfortunately the creature side of her has a dangerous appetite for male sexual vitality, specifically Roger's, and this could render him dead.(Warning: this novel has some gore and deals with aspects of the Succubi that are related with sexuality)
