During the overthrow of the Mexican government, Beatriz’s father was executed and her home destroyed. When handsome Don Rodolfo Solórzano proposes, Beatriz ignores the rumors surrounding his first wife’s sudden demise, choosing instead to seize the security that his estate in the countryside provides. But Hacienda San Isidro is not the sanctuary she imagined. When Rodolfo returns to work in the capital, visions and voices invade Beatriz’s sleep. The weight of invisible eyes follows her every move. Rodolfo’s sister, Juana, scoffs at Beatriz’s fears. But why does she refuse to enter the house at night? Why does the cook burn copal incense at the edge of the kitchen and mark the doorway with strange symbols? What really happened to the first Doña Solórzano?

As the daughter of a rancher in 1840s Mexico, Nena knows a thing or two about monsters. Her home has long been threatened by tensions with Anglo settlers from the north. But something more sinister lurks near the ranch at night, something that drains men of their blood and leaves them for dead. Something that once attacked Nena nine years ago. Believing Nena dead, Néstor has been on the run from his grief ever since. But no amount of drink can dispel the night terrors of sharp teeth; no woman can erase his childhood sweetheart from his mind. When the United States invades Mexico in 1846, the two are brought abruptly together on the road to war. But the shock of their reunion is quickly overshadowed by the appearance of a nightmare made flesh.
