Just ask those mountains over there. They have heard these stories before. They have witnessed the floods. Through the travels of a Mesolithic Marsh Girl, Peter Stevenson tells the folk tales of the sea along the Welsh Coast Path. From bridge-dwelling bwbach and drunken mermaids, to swan girls, salmon children and the pirate Leekie Porridge of Tenby – follow Môrwen on a journey that blends past and present and explores the social and environmental change that is carved into the Welsh coastline.
