When Ailsa Reid becomes the subject of a trial by media after an incident at the school where she works, she escapes to the comfort of her grandparents’ house in Fife. But she arrives to find her grandmother, Moira – recently diagnosed with dementia – has gone missing, and her grandfather, Rupert, gravely injured. Desperate to ensure Moira’s safe return, Ailsa must rely on the help of her estranged mother, Rowan, who abandoned her at birth. Tensions simmer between the two women as they attempt to piece together the lead-up to Moira’s disappearance. But in order to move forward and find Moira, both Ailsa and Rowan must go back to the beginning; to a story about witches burned on the hill above the Reid house centuries ago, and the curse laid upon the women that came after. Can they break the bonds of history in time to save their family? Or will the Reid curse be their undoing?
