In August 1914, polar explorer Ernest Shackleton boarded the Endurance and set sail for Antarctica, where he planned to cross the last uncharted continent on foot. In January 1915, after battling its way through a thousand miles of pack ice and only a day's sail short of its destination, the Endurance became locked in an island of ice. Thus began the legendary ordeal of Shackleton and his crew of twenty-seven men.For ten months the ice-moored Endurance drifted northwest before it was finally crushed between two ice floes. With no options left, Shackleton and a skeleton crew attempted a near-impossible journey over 850 miles of the South Atlantic's heaviest seas to the closest outpost of civilization. Their survival, and the survival of the men they left behind, depended on their small lifeboat successfully finding the island of South Georgia,a tiny dot of land in a vast and hostile ocean. In Endurance , the definitive account of Ernest Shackleton's fateful trip, Alfred Lansing brilliantly narrates the harrowing and miraculous voyage that has defined heroism for the modern age.
