In 1915, Sir Ernest Shackleton's attempt to traverse the Antarctic was cut short when his ship, Endurance, became trapped in ice. Throughout the long, dark Antarctic winter, Shackleton fights for his life and the lives of his men - enduring freezing temperatures, a perilous lifeboat journey through the ice-strewn sea, and a punishing march across the South Georgia glaciers to seek the one slim chance they have of rescue. No previous biographer has experienced even a tiny taste of the polar hell on earth endured by Shackleton and his men. That cannot be said of Sir Ranulph Fiennes, who has been described as 'our greatest living explorer'. From Shackleton's pursuit of adventure as a young merchant seaman, through his rivalry with Captain Scott, to the two remarkable expeditions to Antarctica that revealed his unrivalled leadership and courage, Fiennes brings the story vividly to life in a book that is part celebration, part vindication and all adventure.
