If you enjoy tales of survival against the odds, I highly recommend Deep Survival by Laurence Gonzales [1]

It recounts multiple amazing tales of survival against the odds, then goes into the psychology of what's needed to survive such a situation. Finally, it lists the top 10 traits exhibited by survivors of these kinds of situations.

Not just psychology but neurochemistry as well, some really deep nature-vs-nurture stuff in there. Great book, as a technical diver and divemaster I got a lot from it.
