Although I've never climbed in my life, I absolutely loved this novel. It described certain aspects of human behaviour - the tedium of daily life, the desire for escapism, and the ultimate pointlessness of life-avoidance tactics - like nothing else I've ever read. Although inclined to be dour and depressing, the book's scattered with incredible moments of beauty, humour (the adrenaline-junkie who, on falling off a rock-face into a tree, enjoys it so much that he does it again) and surrealism (the feral Scouts and Guides who roam the Pennines). Everyone should read this book.
