In this powerful novel set in England in the age of witch hunts, Issy doesn't know who she is or where she comes from. Every night she dreams of burning in a fire and at the heart of the flames is a face she dare not look at. Fear and superstition are everywhere and life is dangerous for Issy as she runs from the Witch-finder, from the evil hag who wants her and from those she loves - and maybe from her own true nature.
