Three teenagers have vanished from Ohio's Amish country. The only thing they have in common, other than their religion, is they are keen to leave the Plain Life. Chief of Police Kate Burkholder is called in to consult by Agent John Tomasetti as her Amish roots will be invaluable in an investigation involving this sectarian society. They travel to the small town of Monongahela Falls to investigate the latest disappearance -- that of seventeen-year-old Annie King. The only evidence left behind is a satchel -- and a pool of blood.
The case moves closer to home for Kate when a young relative, Sadie Miller, vanishes. With her own past resonating, Kate delves into the lives of the missing teens. Soon, a sinister pattern emerges along with a vital clue that changes everything. While following up on a lead, Kate makes an appalling discovery and unearths a secret no one could have imagined--thrusting her into a fight to the death with a merciless killer.
