Explore the political, cultural and mythical history of Wales, and get a glimpse of what lies ahead for us all when it comes to climate change, with writers Tom Bullough and Julie Brominicks. In Sarn Helen, Bullough takes us on a walk along Sarn Helen – Helen’s Causeway – the old Roman Road that runs from the south of Wales to the north, weaving in conversations with climate scientists and showing the likely impact of climate change on Wales, while Brominicks celebrates the language, landscape, peoples and biodiversity of Cymru past and present in The Edge of Cymru, exploring themes of belonging and cymreictod (Welshness), trying to find clarity, courage and possibility in the environmental crisis.
