A werewolf released from prison lives solely for revenge. After sweeping every table at Las Vegas’ underground casinos, he learns his true foes are not gangsters, but the millennium-old Senate that hunts mixed-blood species. To rescue his vampire lover, who stole top-secret files for him, he must strike a symbiotic pact with the primordial wolf spirit dwelling inside him—shifting from suppression to side-by-side alliance. And all of this is merely the first move to overthrow the Senate.
