From one of our greatest nature writers: how swifts act as a window into the unity of the living world.

Mark Cocker spends a single midsummer day tracing the flight of swifts - birds that connect continents, climates and species. What begins as a quiet act of observation expands into an awe-inspiring reflection on the interdependence of life on Earth.

Cocker moves from the skies above Britain to the deep ocean currents, solar energy and ecosystems that sustain all living things. This is nature writing of rare insight, beauty and vision - a hymn to the marvel of movement and connection that binds our planet together.

'A jewel of a book' Caroline Lucas

'A beautiful, brilliant, mind-stretching and soul-flying book. Genius.' Horatio Clare
