Exploring the tidal reach of the Orwell Estuary, Arnott guides the reader through its landscapes, wildlife, history and human use. From marshes and mud-flats to shipyards and leisure craft, the estuary’s natural richness and industrial past intertwine. He records birdlife, salt-marsh vegetation and the rhythms of tides alongside the ports, ferries and sailing clubs that animate its shores. Humble stones, windswept banks and busy quays combine to show how nature and people shape this changing Suffolk waterway.
