One second after
by William R. Forstchen
Easy to read story depicting how quickly our very civilized societies can be returned to the middle ages, feudal systems, sky high death rates and even cannibalism. A real page turner, which I finished over the course of a week. The back story is a little too "we're American, how could this happen", but the detail of what happens when anything electrical stops working is all too alarming. Highly recommended.
