In one brilliant adventure over the course of a year, leading historian and nature writer David Gange kayaked the coasts of Atlantic Britain and Ireland from north to south: every cove, sound, inlet, island. Paddling alone in sun and storms, among whales and seabirds, Gange travelled slowly and close to the water as millions did when coasts were the main arteries of trade and communication. He was in search of island archives and the vast poetic literatures of coastal towns, of neglected social histories that unlock our understanding of this archipelago's past and future. In captivating prose and loving detail, this is a history of Britain and Ireland like not other.
