In his first book since the acclaimed The Running Sky Tim Dee tells the story of four green fields. Four fields spread around the world: their grasses, their hedges, their birds, their skies, and their natural and human histories. Four real fields - walkable, mappable, man-made, mowable and knowable, but also secretive, mysterious, wild, contested and changing. Four fields - the oldest and simplest and truest measure of what a man needs in life - looked at, thought about, worked in, lived with, written. Dee's four fields, which he has known for more than twenty years, are the fen field at the bottom of his Cambridgeshire garden, a field in southern Zambia, a prairie field in Little Bighorn, Montana, USA, and a grass meadow in the exclusion zone at Chernobyl, Ukraine. Meditating on these four fields, Dee makes us look anew at where we live and how. He argues that we must attend to what we have made of the wild, to look at and think about the way we have messed things up but also to notice how we have kept going alongside nature, to listen to the conversation we have had with grass and fields. Four Fields is a profound, lyrical book by one of Britain's very best writers about nature.
