Into Thin Air. http://www.amazon.com/Into-Thin-Air-Personal-Disaster/dp/038... Amazing story, super inspirational, and lots of great history. My wife and I both loved this book and could not set it down.
I second this book too although I read several years ago. AND it's relevant in our startup life in a surprising way. I often found myself make much better decision when I'm a bit detached, which is one of 'the' lessons people learned from that accident. So now in our startup, my business partner does all the client/customer/user communication works and I had the precious opportunity to sit back and observe.
(Medium Raw, a 2010 book, was also pretty good --- although probably only if you're into the high-end restaurant scene).
