Ciertas cosas oscuras

Domingo, a lonely garbage collector living on the streets, tries to survive in an uncaring and threatening city when a jaded vampire on the run appears in his life. Atl, descended from Aztec blood drinkers, is intelligent, beautiful and dangerous, and Domingo is mesmerized. Atl needs to quickly escape from the city, away from the rival narco-vampiric clan that relentlessly hunts her down. She also requires an assistant and Domingo is perfect for that job. Her plan doesn't include making new friends, but little by little Atl grows fond of the young man and her undeniable charm. As the trail of bodies spreads out behind them, the local police and mob bosses draw ever closer.
