The pace is much slower relative to other titles in the action / adventure genre. This is not bad in itself, but if you are expecting a straight to the point recollection of the author's journey on Mount Everest you will be disappointed. The book spends at least +50% of it's time describing in intricate detail the background of every individual that was remotely connected to the story . Although typically additive - in this case it can simply feel overwhelming as a result of the sheer number of people described and how few actually had a direct involvement in the story. The experience of reading this book is somewhat akin to watching a movie that has a pop-up ad every 5 minutes. The main story line probably accounts for 3 chapters of the entire book.
The author meant it to read this way (as described in the introduction) which is fine - but, the book is being marketed as a thrilling adventure biography when it reads closer to a history book. Hopefully the above provides additional clarity on what to expect prior to purchase
