The highly anticipated new book from the internationally bestselling, prize-winning author of Landmarks, The Lost Words and The Old Ways 'You'd be crazy not to read this book' The Sunday Times 'Underland is a magnificent feat of writing, travelling and thinking that feels genuinely frontier pushing, unsettling and exploratory' Evening Standard Discover the hidden worlds beneath our feet... In Underland, Robert Macfarlane takes us on a journey into the worlds beneath our feet. From the ice-blue depths of Greenland's glaciers, to the underground networks by which trees communicate, from Bronze Age burial chambers to the rock art of remote Arctic sea-caves, this is a deep-time voyage into the planet's past and future. Global in its geography, gripping in its voice and haunting in its implications, Underland is a work of huge range and power, and a remarkable new chapter in Macfarlane's long-term exploration of landscape and the human heart.
