The Green Hill collects these letters alongside Sophie's account of the years following Felix's death, into which she weaves poignant memories of his life. What results is a deeply moving, beautifully captured record of how - amid the rivers and rocks of Dartmoor, and in the sea off the South Devon coast - Sophie was able to hold on to and nurture her bond with Felix, both in her mind and through a physical engagement with the landscape: actively mourning, rather than grieving.

This book is a celebration of the natural world and the role it plays in our lives and relationships, as well as an examination of how beauty and the passing seasons can help us contend with our own mortality. Above all, The Green Hill is one woman's story of navigating through trauma and loss, and towards a fragile, complicated kind of joy.
