In a world without power, how far will one man go to save his son?

On the five-year anniversary of his wife Hannah’s disappearance, small-town cop Noah Sheridan takes his son Milo to a local ski resort to remember—and to heal. Then the impossible happens. Everything electronic dies. The power grid fails. Cars stall. Phones go dark.

In an instant, their trip becomes a desperate fight to stay alive.

When a white-out blizzard slams Michigan, the town is cut off from the rest of civilization. The of law swiftly collapses along with the power grid. The frigid cold sets in. Food supplies dwindles. Neighbors turn against neighbors.

Noah must make impossible choices, forge uneasy alliances, and face enemies unlike any he’s ever known. At the end of the world, he’ll have to risk everything to save his son and protect the home he loves.
