It's the summer of 1962, middle of the Cold War, and the O'Brien family has moved off-grid to the Mojave Desert in Southern California. After all, the desert has to be a safer place to raise a family than the crime-ridden city, and there they can build a new future. But evil also stalks dusty desert roads, and eight-year-old Nonni finds herself harboring a terrible secret: Only she can identify the predator who has been terrorizing the community. And he knows where she lives.
