In this electrifying thriller by New York Times bestseller Linda Castillo, Kate Burkholder goes undercover in an isolated and secretive Amish community where evil lurks just beneath the surface. Chief of Police Kate Burkholder is called upon by the sheriff's department in rural, upstate New York to assist on a developing situation that involves a reclusive Amish settlement and the death of a young girl. Unable to penetrate the wall of silence between the Amish and "English" communities, the sheriff asks Kate to travel to New York, pose as an Amish woman, and infiltrate the community. Kate's long time love interest, State Agent John Tomasetti, is dead set against her taking on such an unorthodox assignment, knowing she'll have limited communication - and even less in the way of backup. But Kate can't turn her back, especially when the rumor mill boils with disturbing accounts of children in danger. She travels to New York where she's briefed and assumes her new identity as a lone widow seeking a new life. Kate infiltrates the community and goes deep under cover. In the coming days, she unearths a world built on secrets, a series of shocking crimes, and herself, alone... trapped in a fight for her life.
