'I have never read a novel this slender that holds inside it quite so much. Wild, calm, dark yet hopeful... This book ratcheted the breath out of me so skilfully that as soon as I'd finished, the only thing I wanted was to read it again' Jessie Burton

It is high summer in rural Northumberland. Seventeen-year-old Silvie and her parents have joined an encampment run by an archaeology professor with an interest in the region's dark history of ritual sacrifice. As Silvie finds a glimpse of new freedoms with the professor's students, her relationship with her overbearing father begins to deteriorate, until the haunting rites of the past begin to bleed into the present.
