Today I finished Endurance by Alfred Lansing. Of all the books I've read, it's probably the most understandable and easy to consume. Not once did I have to go back or think hard about who a character was or something that had happened. It's a book detailing Ernest Shackleton's attempted expedition to the Arctic along with his crew of 27, and their following escape and rescue after their boat was crushed in the ice. It's a very motivating book.
