Triathlon related book

Can anyone recommend a good book about triathlon. Not necessarily training related but more stories, history or the mental approach to an IM. I’ve got a 5 hour flight coming up and would like to stay busy.

Iron Will by Mike Plant. It’s out of print, but you can usually get a used copy through Amazon for around $20-$30. Velopress should really re-release this.

Not triathlon, but

Once A Runner (running)
Running with the Buffaloes (running)
Gold in the Water (swimming)
Lance Armstrong’s War (cycling)
Swimming to Antarctica (swimming)
