From the author of Addlands, and featuring illustrations by Jackie Morris, an immersive and evocative non-fictional journey through Wales and a revelatory meditation on the nation's past, present and future.

Sarn Helen - Helen's Causeway - is the old Roman Road that runs from the south of Wales to the north. As Tom walks the route, sometimes alone, sometimes in company, he describes the changing landscape around him and explores the political, cultural and mythical history of this country that has been so divided, by language and by geography. Running alongside this journey is the story of Tom's engagement with the issue of the climate crisis and its likely impact on the Welsh coastline. From one of Wales' most celebrated writers, Sarn Helen is at once a vivid and immersive portrait of a nation, and a resonant meditation upon the way in which we are shaped by place and in turn shape the places - potentially irrevocably.
