In the cornfields of Nebraska a woman is found murdered, strung up on a pole, the victim of a deranged killer. It doesn’t take long for the police to realize a serial killer is on the loose—and that his spree has just begun.

Detective Mackenzie White, young, tough, smarter than the aging, chauvinistic men on her local force, finds herself called in grudgingly to help solve it. As much as the other officers hate to admit it, they need her young, brilliant mind, which has already helped crack cold cases that had left them stumped. Yet even for Mackenzie this new case proves an impossible riddle, something the likes of which she—and the local force—have ever seen.
