The world as they know it ceases to exist because of a global power outage. Is it a terrorist attack . . . or something far worse?

Birmingham, Alabama, has lost all power. Its streets are jammed with cars that won’t start, its airport 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. Will they hoard their possessions in order to survive—or trust God to provide as they share their resources with those around them? Yesterday’s world is gone. Family and community are all that remain. And the outage is revealing the worst in some.

Desperation can be dangerous when a killer lives among them.

New York Times bestselling suspense author Terri Blackstock weaves a masterful what-if novel in which global catastrophe reveals the darkness in human hearts—and lights the way to restoration for a self-centered world.

“Blackstock is absolutely masterful at bringing spiritual dilemmas to the surface and allowing readers to wrestle with them alongside her characters.” —RT Book Reviews, 4.5 stars (of Dawn’s Light)
