Incubus Dreams by Laurell K Hamilton
As consultant to the Regional Preternatural Crime Investigation Unit, Anita's called in on what appears to be a case involving a serial killer - a vampire serial killer - who may be preying on strippers. She's sure that none of the local vamps are responsible - but her judgment may be clouded by a conflict of interest. For she is, after all, the consort of Jean-Claude, the ever-intoxicating Master Vampire of the City - something that both her human friends and her ex, the alpha werewolf Richard, are quick to point out. Surrounded by suspicion, overwhelmed by her attempts to control the primal lusts that continue to wrack her as a result of her passionate contacts with vampire, werewolf, and the shapeshifter Micah, Anita does something unprecedented. She calls for help.
