One shocking afternoon, computers around the globe shut down in a viral catastrophe. At sixteen-year-old Adam Daley's high school, the problems first seems to be a typical electrical outage, until students discover that cell phones are down, multiple utilities are failing, and the only vehicles that function are a few ancient, computer-free cars like Adam's.  Driving home, Adam ecounters a storm tide of anger and fear as the region becomes paralyzed. Soon--as resources dwindle, crises mount, and chaos descends--he will see his suburban neighbourhoodband together for protection. And before long, Adam will discover that having a police captain for a mother and a retired government spy living next door are not just the facts of like but the keys to his survival.  Welcome to the all-too-possible nightmare of The Rule of Three.
