I didn‘t remember from my first listen to this book just how much climbing Everest is a business and that there are/were several different expedition groups at one time. Also, didn‘t know at the time there was a controversy surrounding Krakauer‘s account. In his defense, he does make it clear he has not relied on his memory alone given climbers‘ perceptions are impacted by hypoxia. Anyway, I don‘t think he‘s claiming his account is definitive.
