Rescue of Roy Hallums

Pretty cool that they are using the actual video from the helmet cam and not stock footage of the rescue for the advertisement. Adds a bit legitimacy to it.
A couple years ago I saw him speak at a conference about his ordeal. Awesome dude.
Just wondering, has anyone here read this book? If so, what did you think of it? Seems like his experience should be a fascinating read, but I've read mixed things about the book itself.
I could put the roll-up on here.. but wondering of spillage for any of it. No classification markings.
