Sarah Yoder is learning to help the people in her Amish community as a Dokterfraa, creating teas and tinctures using the herbs she grows. But her latest patient seems to have a problem that can't be resolved with anything in Sarah's garden-a woman who, in Sarah's mind, would flourish anywhere but in the place she lives. Meanwhile, Sarah's relatives have decided to do a little matchmaking between her and a visiting Amish man. He would make a wonderful husband, and she knows she should be willing for God to 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 a line of his work for their catalog. The trouble is that they want to market him as Amish. Though he was raised in the faith and now lives in Amish country, he has never joined church-and doesn't plan to, either. Which means that, despite the attraction between them, he must keep his distance from Sarah. But what happens when Sarah and Henry are called upon to help a runaway whose family is too worldly to see how lost their son has become? The plant Sarah calls Keys of Heaven may be able to grow in impossible places, but it's not so easy for people to find their own place. Which means it's quite a temptation for her to take matters into her own hands...
