High summer in Acker's Gap, West Virginia--but no one's enjoying the rugged natural landscape. Not while a killer stalks the small town and its hard-luck inhabitants. County prosecutor Bell Elkins and Sheriff Nick Fogelsong are stymied by a murderer who seems to come and go like smoke on the mountain. At the same time, Bell must deal with the return from prison of her sister, Shirley--who, like Bell, carries the indelible scars of a savage past.
