Boukreev is the Russian guide who was blamed by Krakauer for much of the 1996 tragedy. Many people, including me, believe Boukreev was a superhuman hero that night.
The book's not well written, but it's certain a good rebuttal to Krakauer's account.
Dark Summit: The Extraordinary True Story of Everest's Most Controversial Season, by Nick Heil, is an interesting story of Lincoln Hall. Hall was left to die close to the summit of Everest but survived the night. That was during 2006, a year that saw a large number of Everest deaths.
Most of the great climbers have written books with ghostwriters, but no ghostwriters match Krakauer's talents.
You may also want to read Seven Summits, by Dick Bass, which I linked in a comment above. The true story? Two millionaires, Dick Bass and Frank Wells, are looking for an adventure and way to spend their time. Bass learns that no man had ever climbed the highest peak on each of the seven continents, so Bass and Wells set out to do so - and Bass finally succeeds. It's an everyman story written by two millionaires who weren't climbers when they started. Marty Hoey dies.
I became fascinating with climbing nonfiction in the mid-1990s and spent six or seven years reading whatever I could find. Almost all of the Everest books written before or during that period mention Hannelore Schmatz's body.
Lincoln Hall's night on the mountain is very nearly unbelievable. There were times when I thought Krakauer was drifting into fiction, maybe even science fiction. I can only surmise Hall willed himself to live.
