Policewoman Kat Lindley is running from the big-city job that nearly got her killed, and from memories of the abused boy she failed to save. She agrees to undertake a dangerous masquerade within the peaceful Amish community of Maplecreek, desperate to save its children.

Widower Luke Brand is a leader in the Amish community. But his people are under attack from unknown assailants. The community is reluctant to turn to the outside world - until a particularly vicious assault forces Luke to seek help.

Together Luke and Kat are determined to bring justice to the perpetrators, while struggling to suppress the unspoken and forbidden feelings growing between them. But when the case takes a deadly turn, Kat must race to uncover the menace that threatens the people she has grown to deeply respect - before Luke becomes the next victim.
