At the age of forty, psychiatrist Roger Darvell discovered vampires are real, a nonhuman species living secretly among the ordinary mortals who vastly outnumber them, and he himself is a hybrid, with a vampire mother and a human father. After learning the truth about the craving for blood that had plagued him all his adult life, he came to terms with his "monstrous" side and found love with his human professional partner, Dr. Britt Loren. In between treating their mundane patients, Roger and Britt occasionally venture into problems of the paranormal. They deal with three extraordinary cases in these stories, as they counsel a neurotic young vampire, a guilt-ridden werewolf, and a woman who owns a haunted antique desk.
