East Prussia is no longer on any map, though it was once a thriving land, famously military, deeply forested, artistically fertile, and the birthplace of Immanuel Kant. As the scene of Stalin's 'terrible revenge' it came to embody the turbulence of the twentieth century, was carved up between Poland and the USSR after World War II  and passed abruptly into history. Embarking on a remarkable journey through landscape and memory, Max Egremont has woven the stories of ghosts and survivors into an evocative and deeply moving meditation on identity and the passing of time.
