it details Earnest Shackleton and his party's account of being stranded in the ice flows outside of Antarctica. Their original goal was a transcontinental traverse of Antarctica (in 1915), but they had to abandon it when their ship was crushed by the ice.

The rest of the book details their survival (I believe it took 18 months) and what it took to get rescued.

The book is absolutely phenomenal, and if you get the audible version, the reader is excellent. You can almost feel the cold.

If it was a major motion picture, it would be given bad reviews, they'd claim that a Marvel movie is more realistic. What those guys did is mind-blowing and just defies the odds. What the human body is capable of surviving just amazes me.

Anyway, if you've never heard the story, read the book. I don't want to spoil anymore.
