'Into the underland we have long placed that which we fear and wish to lose, and that which we love and wish to save . . . 'From the vast underground mycelial networks by which trees communicate to the ice-blue depths of glacial moulins, and from North Yorkshire to the Lofoten Islands, Robert Macfarlane traces a voyage through the worlds beneath our feet. He reaches back into the deep history of the planet, through the layers of rock and ancient buried objects, and forward to the future, the legacy of the anthropocene and the world we bequeath our descendants. Underland is Macfarlane at his dazzling best - the lyrical, the political and the philosophical come together in this profound exploration of the relationship between landscape and the human heart.
