A hagtale, a dark fable, a story told around winter’s fires and known to Shakespeare but never written down. Until now. In eleventh-century Scotland, feral wolf-child Wulva is brought up by witches and then sent to live at a Scottish castle, where she falls under the spell of cruel, ambitious Lord Macbeth. Three hundred years later, gentle Brother Rowan goes on a strange and perilous journey to a remote and ancient monastery to write a history of the Scottish king-line. Misfits in their own time, seekers after truth, Wulva and Rowan are deeply connected despite the centuries that separate them. Hagtale explores the power of stories lost and found, their transformative potential, and who gets to be the owner of the tale.
