Nature writer Roger Deakin 'wild swims' his way across England, Scotland and Wales, starting in the moat of his 16th Century farmhouse in Suffolk during a thunderstorm. Deakin swims in rivers, lakes, streams, ponds, lochs, bogs and the North Sea. The book becomes an account of the health of Britain's water systems, the healthiness of swimming in cold water, the subversive nature of outdoor swimming (not everyone is endeared to his public dips). I thought this book might get tedious (how much can you write about swimming outdoors?), but I didn't want it to end. Deakin's descriptions of swimming locales, engagement with local residents, and the historical/political/environmental view of swimming in Britain is fascinating, and his appreciation of and engagement with the natural world is inspirational. It really is a remarkable book with a wonderful finish. Highly recommended.
