Certain dark things

"[Street kid] Domingo ... is busy eeking out a living when a jaded vampire on the run swoops into his life. Atl, the descendant of Aztec blood drinkers, must feast on the young to survive and Domingo looks especially tasty. Smart, beautiful, and dangerous, Atl needs to escape to South America, far from the rival narco-vampire clan pursuing her. Domingo is smitten. Her plan doesn't include developing any real attachment to Domingo ... Little by little, Atl finds herself warming up to the scrappy young man and his effervescent charm. And then there's Ana, a cop who suddenly finds herself following a trail of corpses and winds up smack in the middle of vampire gang rivalries"--Provided by publisher.
