What should you do when you discover that you're the child of witches?
This is the predicament which faces Jennet Device. An illegitimate and lonely child, Jennet can only look on in horror while her family engage in the dark side of the folk magic learned from her grandmother, the notorious cunning woman known as Old Demdike. As terrifying tales of bewitchment and murder sweep through the Forest of Pendle, Jennet is forced to realise the power of their vengeance, and her powerlessness to stop it.
When her family's practices come to the attention of the local sheriff, Jennet suddenly finds herself at the centre of a witch trial which could destroy them all. The little girl from Pendle is now the court's star witness, and she has a terrible choice to make: can she bring herself to lie to protect them, or find the courage to tell their stories to the world even if it could cost them their lives?
