Vampire Huntress Legend, book 07: The Forsaken
L. A. Banks2006

The Body of a Goddess...with the Heart of Hell itself.
The Chairman of the Vampire Council is dead, and Lilith, the consort of the Unnamed One, and the Unnamed One himself are out for revenge against Damali Richards, the Vampire Huntress, and her lover, Carlos Rivera. A ruthless and carefully planned strategy---one that not even Damali will anticipate---has been developed. There is only one entity who can best Damali, send Carlos packing, and put the Guardian team at mortal risk. This powerful being was once banished into a forsaken land and possesses everything that would bring a Neteru to his or her knees. This time the fight is not so clear-cut, and it is not only Damali's soul in the balance but her body and heart as well.
