Book excerpt: There is the Cornwall Lamorna Ash knew as a child - the idyllic, folklore-rich place where she spent her summer holidays. Then there is the Cornwall she discovers when, feeling increasingly dislocated in London, she moves to Newlyn, a fishing town near Land's End. This Cornwall is messier and harder; it doesn't seem like a place that would welcome strangers. But before long, Lamorna finds herself on a week-long trawler trip with a crew of local fishermen, afforded a rare glimpse into their world, their warmth and their humour. Out on the water, miles from the coast, she learns how fishing requires you to confront who you are and what it is that tethers you to the land. Dark, Salt, Clear is a bracing journey of discovery and a captivating portrait of a community sustained and defined by the sea for centuries.
