The lights didn't just flicker, they died. And they aren't coming back.
When a silent pulse brings Atlanta to a standstill, Marcus Cole is trapped fourteen floors up, looking out over a city that has just become a graveyard of dead technology. No phones. No cars. No rules.
Everyone else is waiting for help. Marcus knows better. He's seen how fast a civilization can tear itself apart, and he knows he has exactly seventy-two hours before the exit routes become war zones.
With nothing but what he can carry and a past he's tried to outrun, Marcus must cross a disintegrating landscape to reach the only thing that matters. But in a world where everyone is a predator, the shortest path home is the most dangerous, and the man he used to be might be the only version of him that survives.
