This "certain dark thing" broke through my reading slump, and made me excited about reading again. Set in a "neon noir" Mexico City where vampires hide from Sanitation sweeps, a modern detective with a Van Helsing reputation gets swept up in a blood drenched turf war, and somewhere, a dreamy young garbage picker rides the subway across from a beautiful ... woman. I got swept away—along with Domingo, Atl, and a worldly melange of mythologies—into a world of drug cartels, vampire clans and romance.
