Serendipity, that's what we have here. Over 100 years ago, Shackleton and his team, including Frank Worsley, sought to be the first to reach the South Pole and to walk across Antarctica. In 2008, Henry Worsley, related to Frank and a Shackleton admirer, along with two other descendants of Shackleton's team, successfully trekked across Antarctica. Worsley returned in 2015. With these two books, you can read how the story began and one of the most recent chapters.
