Damien is the longest-surviving Prince in all of Vampire history, but a scholar he is not. Still, he feels duty bound to visit the recently unearthed Nightwalker Library, a treasure-trove of knowledge about the Vampires, Lycanthropes, and Demons of the earth. And it is in the library that he first encounters Syreena.

Advisor and sister of the Lycanthrope Queen, Syreena is a striking anomaly, for she can take the forms of both peregrine falcon and dolphin—a trait revealed in her two-colored hair and eyes. When she is abducted and tortured by a rogue Demon, it is Damien's life-saving bite that frees her, and leaves her reeling from desire in its wake . . .

The song of Syreena's blood is too powerful for Damien to resist. And as the two predators face off, both ravenous for the touch of the other, rebellion brews in their midst . . .
