Inspired by an incredible true story, by a multi-award winning new star of historical fiction.

1589. Scottish housemaid Geillis and Danish courtier Margareta lead opposite lives, but they both know one thing: when a man cries “witch”, no woman is safe.

Yet when the marriage of King James VI and Princess Anna of Denmark brings Geillis and Margareta together, everything they supposed about good, evil, men, and women, is cast in a strange and brilliant new light.

For the first time in history, could black magic – or rumours of it – be a very real tool for women’s political gain?

As the North Berwick witch trials whip Scotland – and her king – into a frenzy of paranoia, the clock is ticking. Can Margareta and Geillis keep each other safe? And once the burnings are over, in whose hands will power truly lie?
