Aiden lived for five years in the ruins of the apocalypse, only to be betrayed by the brother he had saved from the jaws of zombies and pushed from the fifth floor into a horde. He woke up, reborn, and his alarm clock showed 180 days until the apocalypse. A lottery ticket, his grandmother's valley, and a six-meter-high wall – he turned his home into a fortress, despite everyone's ridicule. The apocalypse arrived three days early, and his neighbors knelt outside his door, begging him to open it. But the outside world held more than just zombies – a fifty-person armed gang was entrenched in the old chemical factory, and the radio crackled with hunting signals from Black Flag, the Eastern European mercenaries. A horde of 1.2 million zombies was sweeping in. This time, he wouldn't just defend his walls; he would make all his enemies pay.
