Exquisitely written and impossible to put down, The Hill in the Dark Grove is a haunting and sinister story embedded in Welsh folklore. Moving and chilling in equal measure, it is about a lost way of life and the terrifying lengths we go to to protect what we know. Carwyn and Rhian - the last in a long family line of sheep farmers - are living out a brutal year in their hillside farm, deep in the mountains of Eryri, North Wales. When Carwyn stumbles across a stone circle in one of the fields on their land, his curiosity quickly descends into obsession. His wife, Rhian, meanwhile, is confronted with the growing realization that the man with whom she shares her life and home is becoming a frightening stranger. As the harsh winter closes in, Rhian finds herself alone with her increasingly peculiar husband, the mountains and the looming megalithic stones . . .
