Amish widow Sarah Yoder has been struggling to raise her two teenaged sons and provide a home where family and members of her Old Order Amish church can find fellowship and friendship. Though she is close to her in-laws, lately it feels like her relationship with her boys is splintering. Her stepson Simon wants to move out west with his cousins to find work. And her youngest, Caleb, is spending far too much time over at the tumbledown home of a man who left the church long ago. Henry Byler only returned recently to Willow Creek when he inherited the family farm--under protest--and now seems caught in a struggle between the faith of his childhood and the world he's come to know.
Ruth Lehman, the local Dokterfraa, believes Sarah should use her gift for growing plants to become an herbal healer, too. Sarah is reluctant, however, uncertain if caring for others will take her away from her family--the place where she believes God wants her. But when she feels called to help members of her community, she soon discovers that the heart can be scarred as deeply as the body. As she compiles her herbs, she waits for God to do his healing work in a man who rues a harsh decision, in a lonely prodigal who has lost everything, and maybe even in a herbalist-in-training who firmly believes she will never love again.
