The best preparedness book I have read is "Patriots: the Coming Collapse" By James Wesley Rawles. A fast paced novel, but filled with factual and useful information. Rawles is working on a non-fiction "Rawles on Relocation" to be released later this year, with more details on where to live, and setting up a sensible home.
