To write about Hell, it helps if you have been there. In 1915, Sir Ernest Shackleton's attempt to traverse the Antarctic was cut short when his ship, Endurance, became trapped in ice. The disaster left Shackleton and his men alone at the frozen South Pole, fighting for their lives. Their survival and escape is the most famous adventure in history. 'Shackleton' is an engaging account of the adventurer, his life and his incredible leadership under the most extreme of circumstances.
