3.5/5 Bit too inspirational for nightmares, so I can‘t say I enjoyed it fully. If you like gritty, semi-realistic, survival stories while waiting to see a train crash - this book might be for you. No zombies or mythical apocalyptic creatures. It‘s basically a crime mystery with the setting of a worst case disaster. Very suspenseful. I greatly appreciate the medical, Native American, LE, psych, and technological perspective/details.
