I was skeptical at first. The editors sort of gave him his own voice, word choice I think, so the style comes across like the writing of an engineer who climbs a lot of mountains. But there was no filler. And these mountain-climber books are all real, above all, so it was very, very absorbing.
My wife usually wants daily updates when I'm reading a good book but in this case she usually declined b/c it was disturbing to her.
Aron has had LOTS of great climbing adventures, so the format interleaves the early chapters of his Utah near-tragedy with earlier awesome things he did. A common pattern to his weekends: he ends up climbing alone in remote places and there is often a rock or other heavy thing falling down on top of him.
I feel the editor's contribution. It feels like the editor suggested the sequencing and maybe the pacing, especially at the end. But then all of the voice, really feels like it's the authors voice. Possibly the editor helped him write in his real voice too.
I reflected and daydreamed about this book when I was away from it.

Unreal

You never quite like Aron as a person. The book is an okay story of survival and a great reminder or warning to NEVER go into the wilderness without telling someone when/where you'll be.

Yeah, the guy had some tough times. Don't make him a good writer!
