In a world where a half-hidden war has finally revealed to ordinary humans the supernatural creatures that surround them, safety is hard to find for a girl like Natividad.
Born Pure, one of the rare girls able to wield protective magic against demonic forces, Natividad and her brothers are on their own and on the run, with terrible memories and terrible enemies behind them. The only possible shelter might be found with their father’s kin, the infamous black dogs of Dimilioc . . . if they can win acceptance. But when their enemies track them to their new home, neither Natividad nor her brothers nor Dimilioc itself may survive . . .
