Query: Its the most gripping true life expedition I've ever read !!

Jon really does an excellent job of making you feel the Victory and the Misery of a mountain expedition. He takes you from hopelessness in one chapter to triumph in the next chapter. I couldn't put the book down. Its an amazing piece of work. Great Job Jon!!! I reccomend it highly
