Stephen Venables and three companions made the first ascent of Panchu Chuli V—a remote Himalayan peak on the borders of India, Nepal and Tibet. A rappel anchor failed on the descent, pitching Venables into a 300-foot fall. Crashing through the black night, flung from rock to rock, he assumed that he was plunging to his death. Against all odds he survived, but was left stranded 19,000 feet above a labyrinth of glaciers and snow slopes with two broken legs, the threat of gangrene, and scant food or medical supplies. If he was to return to his wife and son waiting at home some 5000 miles away, Venables knew he had to draw on his reserve of courage and determination. The third Adrenaline Classic, A Slender Thread is a spellbinding account of Venables' survival—and his intense personal struggle to understand the risks he takes for the sake of his insatiable passion for climbing. He comes as close to anyone to answering the unanswerable question: Why do they do it?
