Book excerpt: In this masterpiece of nature writing, Nan Shepherd describes her journeys into the Cairngorm mountains of Scotland. There she encounters a world that can be breathtakingly beautiful at times and shockingly harsh at others. Her intense, poetic prose explores and records the rocks, rivers, creatures and hidden aspects of this remarkable landscape. Shepherd spent a lifetime in search of the 'essential nature' of the Cairngorms; her quest led her to write this classic meditation on the magnificence of mountains, and on our imaginative relationship with the wild world around us. Composed during the Second World War, the manuscript of The Living Mountain lay untouched for more than thirty years before it was finally published.
