She's a vampire--and not thrilled about it. Payback meet bitch.   Adam Brody hopes Maya is as dangerous as they say she is. He needs her to help rescue his niece Cammie from a ruthless band of vamps, and he's willing to pay--in blood. Trusting her is another matter. Adam has never met a vampire who doesn't lie. Then again, he's never met anyone like Maya, who fills him with a desperate need that ignites into explosive, no-holds-barred encounters . . .   "A wild, adventurous ride readers will love!" --New York Times bestselling author Angela Knight
