Check out Endurance by Alfred Lansing. It's the story of Shackletons failed antarctic voyage and how he survived. Absolutely amazing story and really well written.
This is an excellent story. I thoroughly enjoyed it. I think I saw another comment mention it but after you finish this, you must read (or listen to) "Endurance" by Alfred Lansing. The narration was excellent. I borrowed the audiobook from libby and it was such an amazing story!
