I actually bought this book based on a science show review where the scientist was mentioning how the book tells us importance of atmosphere. I found the reading very good. The actual event of climbing Everest , reaching Summit and then descending back have been very well written , I enjoyed reading it. For somebody who has no experience with mountaineering, the book explains the events, some of the technical details quite well. In terms of experience of buying on Amazon, although the checkout with credit card failed, i opted for COD and got it next day itself. So that was not bad either.
