Sarah Yoder is learning to help the people in her Amish community as a Dokterfraa, creating teas and tinctures from the herbs she grows. But her latest patient seems to have a problem that can't be resolved with Sarah's remedies-a woman who, in Sarah's mind, would flourish anywhere other than where she lives. Meanwhile, as Sarah's relatives attempt a little matchmaking between her and a visiting Amish man, she struggles to let God show her His choice of partner and not allow her friendship with her neighbor, Henry Byler, to grow into anything more.

Henry has seen some success as a potter since a major store commissioned his work for their catalog. But the trouble is they want to market him as Amish. Though he was raised in the faith and lives in Amish country, Henry has never joined church and doesn't plan to. Which also means, despite the attraction between them, he must keep his distance from Sarah. But what will happen when Sarah and Henry are called upon to help a runaway whose Englisch family is blind to how lost their son has become? The plant Sarah calls Keys of Heaven can grow in impossible places, but it's hard for people to find their own place, which creates quite a temptation for Sarah to take matters into her own hands...
