The White Darkness (Doubleday) is his latest book.Henry Worsley was a devoted husband and father and a decorated British special forces officer who believed in honor and sacrifice. He was also a man obsessed. He spent his life idolizing Ernest Shackleton, the nineteenth-century polar explorer, who tried to become the first person to reach the South Pole, and later sought to cross Antarctica on foot. Shackleton never completed his journeys, but he repeatedly rescued his men from certain death, and emerged as one of the greatest leaders in history. Worsley felt an overpowering connection to those expeditions.. He would succeed where Shackleton had failed, in the most brutal landscape in the world. The White Darkness is both a gorgeous keepsake volume and a spellbinding story of courage, love, and a man pushing himself to the extremes of human capacity.
