Having read several very negative reader reviews about this book (especially people condemning the author for being selfish), I was prepared for a bad book. However, it was not the case.
The author is not the best of writers, true. His writing style is lacking, and minute descriptions of booking a ticket or stuffing the pockets of a jacket (for the umpteenth time) are boring. But the descriptions of getting lost in the jungle, getting hurt, trekking treacherous paths? I liked them a lot.
Now, about the selfishness that some people mentioned. It was nonexistent. Perhaps he was overly optimistic, but definitely not selfish. I actually liked his positive attitude, and also his resilience and dedication that, in spite of a serious lack of experience and proper equipment, helped him conquer not one, but two mountain summits.
