When poet Andrew Greig was asked by Scottish mountaineer Mal Duff to join his ascent of the Mustagh Tower in the Karakoram Himalayas, he had a poor head for heights and no climbing experience whatsoever. The result is this unique book. ''Summit Fever'' has been loved by climbers and literary critics alike for its refreshing candour, wit, insight and the haunting beauty of its writing. Much more than a book about climbing, it celebrates the risk, joy and adventure of being alive.
