One of the first things I did when I got my Kindle Fire a month ago, was to research books on Prepping. I've loaded several that were free. many more are available at $0.99 to $2.99 range. There are many for every situation from general surviving and prepping to specific Tornado's, Earthquakes, Nuclear War and other specific scenarios. Go online & check them out!
