If you enjoy books on adventure get a copy of Endurance. It is the story of the Shackleton expedition to the Antarctic in the early 1900s and written by Alfred Lansing. Just an amazing true story. They set out to be the first to cross the south pole by land, which meant dog sled travel. When their ship got close to the Antarctic it got trapped in sea ice, got crushed and destroyed. Instead of a journey lasting months, it took them three years to finally return to civilization. This in one of the most uninhabitable places on the planet. And they all made it back.
