For thousands of years, unseen monsters stalked the world.
Then the miasma that hid the supernatural world disappeared, and ordinary people suddenly saw the truth: monsters had always lived among them, feeding on despair and death.
Natividad can defend against demons with rare protective magic. Her older brother Alejandro is a black dog, sharing his body with a dangerous supernatural shadow. Her twin brother Miguel has no magic at all—only a brilliant mind and an unshakable determination to keep his family alive.
When their parents are murdered and their home destroyed, the three flee to Dimilioc, the last great black dog House. But Dimilioc itself barely survived the war that destroyed the vampires. Powerful enemies surround Dimilioc, old alliances are crumbling, and a terrifying adversary is determined to finish what the war began.
To survive in a world haunted by demons and monsters, courage alone may not be enough. Natividad and her brothers must forge bonds of trust with dangerous allies, face enemies stronger than they imagined, and find a place within a family forged by loyalty, sacrifice, and war.
