Widower Luke Brand is a leader in the peaceful Amish community of Maplecreek. But now his people are under attack from unknown assailants -- and the main target appears to be the children. Although the community is reluctant to turn to the outside world for help, a particularly vicious assault leads Luke to the local police.

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

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 target.
