In 1914 Ernest Shackleton and 27 men set out to cross Antarctica on foot. Before they could even land, their ship, the Endurance, was trapped in the ice of the Weddell Sea, and months later it was crushed and sank. The men camped on drifting floes, then sailed in open boats to a deserted island. From there Shackleton and five others crossed 800 miles of the worst ocean on earth in a small lifeboat to get help. Every man survived. Lansing tells it from the crew\'s own diaries, and it reads like a thriller
