Endurance is the story of Ernest Shackleton's Antarctic voyage in 1914. Imagine setting sail for Antarctica in a single ship, determined to reach uncharted territory, facing known and unknown dangers, without phones, high power radios, or promise of success. Now imagine your ship gets lodged in the ice and you have to make sure your crew survives to see civilization again. This is what Shackleton and his crew faced when their rightly-named ship, The Endurance, halted in the ice for the final time.
Alfred Lansing tells the story in such a way that it's easy to read quickly, not realizing how many pages have been read until a new chapter reminds you. As a work of nonfiction, it's engaging and fascinating. As a work to inspire your own sense of responsibility and dedication, it's refreshing.
I highly recommend adding it to your collection and really taking in the lessons Shackleton and his crew can teach.
