Trudy lost her beloved sisters in eighteenth century Vienna, but she is a survivor. As a half human daughter of the demon Asmodeus, she is a psyvamp, ever young and beautiful. Unlike her dead sisters, she does not engage in relationships with men, instead she moves from club to party, city to city, stealing small amounts of life force from intoxicated young men, never staying long in any one place. She is lonely, but friendships do not work for one like her and relationships with men seem to be deadly for her kind. The Del Fantasma is a unique place, friendly, where she can relax after her nightly hunts and alleviate a little of her loneliness. But Cody introduces her to a man, Professor Gabriel Di Russi, a former priest, a scholar of demonology who once was part of a secret priestly society that studied demons for the Church. He is not like the drunk young men she feeds from, or like the dying old men she sometimes marries. Gabriel is both fascinating and frightening, and he wants to interview her—and she agreed! What has she done?
