Thirteen years before the events happening in the Labyrinth, torrents of solar radiation crashed onto Earth, destroying everything alive on their way… Irreversible climate changes led to a sharp warming. The few survivors of the catastrophe huddle in tents and miserable makeshift shelters, hiding in forests and mountains. To make matters worse, the government decides to reduce America’s population by releasing a deadly, not fully studied virus. Young Mark and Trina, along with their companions—a retired pilot and a former military nurse—make their way across the scorched lands of North Carolina in search of a cure for a terrible contagion spreading relentlessly across the planet.
