When All Hell Breaks Loose is a survival book by Cody Lundin. I've not read survival books before so I don't have a lot to compare this to.
Cody lives in Arizona and has probably done every stupid thing in the world (survival-wise) and lived to tell about it. Which inclufrd eating things that were moldy and spoiled just to see what would happen. He also admits to using Poison Ivy for toilet paper once ...... ONCE.
I almost put this book down because of the inordinate time he spends on the value of good shelter and on maintaining body temperature and hydration. But right after that, things got interesting. Cody does not tell you how to make snares or IEDs, but what he gives is common sense, basic information on survival. The books covers water, food, shelter and hygiene. He covers a range of possibilities from needing just a few days, to living totally off the gird for the rest of you life. He interweaves "green" living with survival. Basic food and water topics are covered as are hygiene and what to put in a bug-out bag. Also covered is consideration of where are you going to bug-out to? (The "toilet paper alternatives" makes good reading while sitting on the throne.)
This probably isn't the normal survival book, but is aimed at people who haven't given it a lot of thought. He spend a good amount of time promoting individualism, which is good. He also admits to many mistakes he's made and how he (and the reader) can learn from them. He admits when there's no clear answer (like "how long does food last").
All in all, I think it's a good book for most of us, unless you're already a hard-core survivalist in which case this book is a little elementary for you.
Combine this book with the fiction novel, Lucifer's Hammer and you'll have a pretty good idea of what to expect for long term survival and how to prepare.
