Ghost Wall - Sarah Moss

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.
