A sensational missing persons case overshadows a darker evil in this supernatural thriller set in the borderlands of Arizona.

Lulu Lavender's mixed-race family has been slaughtered, and she has been taken. But with the high-profile case of a missing white teenager from a wealthy family occupying the attention of law enforcement and the media, it's left to sheriff's lieutenant Buck Shelton and his small, rural office to find Lulu, if he can.

To Buck's growing horror, his quest leads him into a world he never knew existed, where the tendrils of an ancient evil reach right into the torn-from-the-headlines present. On the US/Mexico border, supernatural forces using vigilantes, drug dealers, and innocents as pawns clash in a bloody showdown—and not everyone will survive . . .
