Ghost Wall by Sarah Moss

Teenage Silvie and her parents are living in a hut in Northumberland as an exercise in experimental archaeology. Her father is a difficult man, obsessed with imagining and enacting the harshness of Iron Age life. Haunting Silvie’s narrative is the story of a bog girl, a young woman sacrificed by those closest to her, and the landscape both keeps and reveals the secrets of past violence and ritual as the summer builds to its harrowing climax.
