A dark secret hides in the heart of Maplecreek's Amish community.

One morning Leah Kurtz goes to wake her adopted infant daughter and instantly knows something is terribly wrong. She is convinced that her baby has been switched with another child. Afraid that no one will believe her, Leah turns to an unlikely ally, despite the fact that her Amish community frowns on its members seeking help in the outside world.

Dr. Mark Morelli studies the genetic illnesses that plague the Amish, but he has other, private reasons for coming to Maplecreek . . . reasons that may be tied to the mysterious disappearance of Leah's daughter. Together, Leah and Mark must uncover a conspiracy -- before there are deadly consequences.
