As Kim Willis drifts from the traditional path of marriage and motherhood, she yearns for a new set of stories to light her way. Here, she is pulled towards the source of the Severn, hearing whispers of ancient matriarchs: shape-shifting enchantresses, scaly nymphs and goddesses who once commanded our lands. These are no fair maidens, but powerful warrioresses and animalistic beasts, snaking along the edges of watery places where we meet the otherworld in the shadows.

As she uncovers the ancient myths hidden in the rugged landscapes of the British Isles, the stories of women like Arianrhod, Melusine and Cerridwen awaken a forgotten power. Journeying from the Severn to Skye, Eryri to Northumberland, Kim discovers new magic in the tales of old, unveiling forgotten truths about grief and healing, while charting a new course through sisterhood and sexuality, fertility and freedom.
