Birmingham, Alabama, has lost all power. Its streets are jammed with cars that won't start and its airport is engulfed in flames from burning planes. All communications—cell phones, computers, even radios—are silent. Every home and business is dark. Is it a natural disaster, a terrorist attack, or something far worse?

In the face of a crisis that sweeps an entire high-tech planet back to a time before electricity, the Branning family faces a choice.

Family and community are all that remain. And the outage is revealing the worst in some.

Desperation can be dangerous—especially when a killer lives among them.
