I downloaded the Kindle version of this book-- I'm 26% in and it's pretty sobering stuff. The book is about this successful guy who contracts ALS, and then decides to do the Great Loop by himself as the disease takes over his body. Kind of a "you should hurry and get off your ass and do something" type of story.
