Futile Flame (Vampire Gene, #2)

Gabriele and Lilly have been attacked by something that feels like an Über-vampire, but the texture to the evil is blacker than night and thick enough to choke on and leaves the nearly indestructible vampires physically ill. Gabriele must find his maker, Lucrezia Borgia, to learn more about the vampire race and this demon-like entity that is stalking them. Unfortunately, Gabriele has told Lilly everything about his past except about Lucrezia, and now he’s left wondering how to explain his vampire mother.
