Once you tell someone certain things, like, say, you got mailed a human head in a box, they tend to think you're crazy.
Anita Blake's reputation has taken some hits. Not on the work front, where she has the highest kill count of all the legal vampire executioners in the country, but on the personal front. No one seems to trust a woman who sleeps with the monsters. Still, when a vampire serial killer sends her a head from Las Vegas, Anita has to warn Sin City's local authorities what they're dealing with. Only it's worse than she thought. Several officers and one executioner have been slain - paranormal style...
Anita heads to Las Vegas, where she's joined by three other federal marshals, including the ruthless Edward hiding behind his mild-mannered persona. It's a good thing Edward always has her back, because, when she gets close to the bodies, Anita senses "tiger" too strongly to ignore it. The were-tigers are very powerful in Las Vegas, which means the odds of her rubbing someone important the wrong way just got a lot higher...
Hamilton's 17th Anita Blake novel draws the vampire hunter into a game of cat-and-mouse with a particularly monstrous vampire named Vittorio. Aided by sadistic serial killer Otto Jefferies, convenient sociopath Edward and fanged escorts handpicked by her lover Jean-Claude, U.S. marshal Anita offers her services to Las Vegas, now under siege from Vittorio's army of enthralled preternatural beings. Manipulated by the cunning Vittorio and occasionally misled by coincidental events, Anita employs her insight into Vittorio's condition and weaponized libido as the decisive weapons in this struggle. The book is largely concerned with the melodramatic conflict between hunter and hunter and Blake's soap-operatic love life, but Hamilton does manage some genuinely moving passages, particularly those describing the terror of innocent vampires caught up in the arbitrary and draconian U.S. legal system.
