The intense desert heat has brought horror to a small corner of the Southwest. A body lies lifeless in an airless trailer, surrounded by seventeen others. It is a crime unspeakable in its conception and execution—a nightmare strangely connected to a grisly slaughter in a neighboring state, where the corpses of two women are found tied up, naked, and gruesomely posed on a rancher's land. A day that started out hot has already turned blistering for Joanna Brady, the sheriff of Cochise County, Arizona, for terror has moved into her small town to stay. And the nightmare will not end until she uncovers the roots of a monstrous obsession buried somewhere in the most frightening dark shadows of the past.
