One shocking afternoon, computers around the globe shut down in a viral catastrophe. At Adam Daley's high school, the problem first seems to be a typical electrical outage, until students discover that cell phones are down, municipal utilities are failing, and a few computer-free cars like Adam's are the only vehicles that function. Driving home, Adam encounters a tide of anger and fear as the region becomes paralyzed. Soon — as resources dwindle, crises mount, and chaos descends — he sees his suburban neighborhood band together for protection. And Adam understands that having a police captain for a mother and a retired government spy living next door are not just the facts of his life but the keys to his survival.
