Paramedic Zoe Chambers hoped a week at the Monongahela County Fair, showing her horse and manning the ambulance, would provide a much-needed diversion from recent events that continue to haunt her. An old friend, a bossy nemesis, and a teenage crush from her 4-H days fail to offer the distraction she had in mind. But ever the caregiver, she soon bonds with a troubled teen and a grieving father.

Back in Vance Township, a missing woman turns up dead, leading Police Chief Pete Adams into a journey through her mysterious final hours. With each new clue, the tragic circumstances of her death grow increasingly muddied. A cryptic phone call leads Pete to join Zoe for an evening at the fairgrounds where the annual school bus demolition derby concludes with a gruesome discovery and a new case that may or may not be connected to the first.

Pete's quest for the motive behind two homicides–and Zoe's stubborn determination to reunite a family-thrust them both onto a collision course with a violent and desperate felon.
