The Rule of Three by Eric Walters

As Adam and his classmates are working in the school's computer lab, all power goes out. Everything electronic is dead - no computers, no cell phones, no cars. No cars that is, unless you happen to own a car built before they were run by computers. As Adam and his neighbors start to realize just how widespread the problem is, they realize that things could get really scary  really quickly.
I thoroughly enjoyed reading this book!  Walters does a great job of  detailing the downward spiral of civilization as people become more and more desperate for all things required for life. It really gets the reader in the frame of mind for what it would be like and what we would face if we were to lose power indefinitely.
I highly recommend this title to those readers that enjoy survival stories and post apocalyptic worlds.
