Jon Krakauer writes well, and Into Thin Air is probably his finest book. Tapped to climb Mount Everest in 1996 to write a story about the then new trend in guided ascents up the mountain, Krakauer witnesses the deaths of several climbers and guides in a blizzard, and nearly dies himself.
Even seasoned climbers die on Mount Everest. Its summit is in the jet stream. The human body was not designed to climb to 29,029 above sea level. Even with oxygen and trained guides, accidents and bad weather kill climbers.
They may be no other reason to read this book than the sheer entertainment of it; and this despite the fact that people die, and Krakauer depicts those deaths in detail.
