As the summer draws to a close, a few snowbeds - some as big as icebergs - survive in the Scottish Highlands. Christopher Nicholson's Among the Summer Snows is both a celebration of these great, icy relics and an intensely personal meditation on their significance. A book to delight all those interested in mountains and snow, full of vivid description and anecdote, it explores the meanings of nature, beauty and mortality in the twenty-first century.
