A darkly spellbinding story of witches, sisterhood and coming of age, steeped in Welsh mythology and Arthurian legend.

Ivy has spent years looking for her birth mother, but when she finally finds her on Bardsey Island, she is shocked by what greets her.

According to folklore, the cormorants that fly over the remote Welsh isle are the terrifying witches of Arthurian legend - and they are searching for Ivy. Her mum warned her not to come and to stay away from the lighthouse, but now it's too late. As the shadows draw closer, Ivy must look deep within herself if she wants to survive.

For not every story in folklore is true, and some evils aren't what they seem...

An unputdownable new stand-alone novel from the bestselling author of THE TWISTED TREE and THE CROOKED MASK.
