Yes, this was nonfiction. If you liked the survival story genre and were interested in reading a book about Everest then I would recommend "into thin air" by Jon Krakaur. That's a really interesting book about the 1996 disaster where I think 11 people (or so) died on the mountain. This book was not nearly as interesting as that one.
