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 and some sort of burial mound in one of the fields on their land, he quickly develops an obsession. His wife, Rhian, meanwhile, is confronted with the growing realization that the man with whom she shares her life and home is slowly becoming a frightening stranger. As the harsh mountain winter closes in, Rhian finds herself alone with her increasingly peculiar husband, the mountains, and the looming megalithic stones . . . Exquisitely written and impossible to put down, The Hill in the Dark Grove is a gorgeous story of a lost way of life and the lengths we go to to protect what we know.
