Stories about Everest itself, the first hikers, the first summit, a few background paragraphs about the hikers/acquaintances, what they do, what are their achievements, Krakauer's magazine backstory and such, I left it on Chapter 5 few days ago and I think we are barely arriving to Base Camp.

It's not bad per se, I mean it works as an introductory bit, but I was kind of expecting the book to start at Base Camp. If I am guessing right, the climb will start on Chapter 6 (which is a a quarter of the book according to KOreader), will still try to keep on reading it.
