Isabel Frith, the village midwife, walks a dangerous line with her herbs and remedies. There are men in the village who speak of witchcraft, and Isabel has a past to hide. So she tells nobody her fears about Wulfric, the pious, reclusive apothecary.

Mae, Wulfric's youngest daughter, dreads her father's rage if he discovers what she keeps from him. Like her feelings for Rafe, Isabel's ward, or that she studies from Wulfric's forbidden books at night.
