The five centuries between the end of Roman Britain and the death of Alfred the Great have left few voices save a handful of chroniclers, but Britain's "Dark Ages" can still be explored through their material remnants: architecture, books, metalwork and, above all, landscapes. Max Adams explores Britain's lost early medieval past by walking its paths and exploring its lasting imprint on valley, hill and field. Each of his 10 walking narratives form free-standing chapters as well as parts of a wider portrait of a Britain of fort and fyrd, crypt and crannog, church and causeway, holy well and memorial stone.
