In the summer of 1914, Sir Ernest Shackleton set off aboard the Endurance bound for the South Atlantic. The goal of his expedition was to cross the Antarctic overland, but more than a year later, and still half a continent away from the intended base, the Endurance was trapped in ice and eventually was crushed. For five months Shackleton and his crew survived on drifting ice packs in one of the most savage regions of the world before they were finally able to set sail again in one of the ship's lifeboats. Alfred Lansing's Endurance: Shackleton's Incredible Voyage is a white-knuckle account of this astounding odyssey.
