In 1915, Sir Ernest Shackleton's attempt to be the first to traverse the Antarctic was cut short when his ship, Endurance, became trapped in ice. He and his crew should have died. Instead, through a long, dark winter, Shackleton fought back: enduring sub-zero temperatures, a perilous lifeboat journey across icy seas, and a murderous march over glaciers to seek help. Shackleton's epic trek is one of history's most enthralling adventures. But who was he? How did previous Antarctic expeditions and his rivalry with Captain Scott forge him? And what happened afterwards to the man many believed was invincible? In this astonishing account, Fiennes brings the story vividly to life in a book that is part celebration, part vindication and all adventure.
