Tension builds as the body count increases.

Emily Davis stumbles across a skull while searching for a missing hiker in Hickory Run State Park, and someone goes to great lengths to keep her away from the case.

Boulder Field's national landmark status and its popularity makes it impossible to keep the story out of the national press, and a viral video puts Emily in the cross-hairs of a serial killer.

The sergeant assigned to investigate the case is none other than her high school sweetheart, Wade Brunner. The Butcher of Boulder Field must be stopped. Emily and Wade will need to work together to end his reign of terror.
