The zombie apocalypse isn't coming, it's already here. "He awoke and, for the first time in almost twenty-five years, remembered who he was." Twenty years after Z-Day, a handful of survivors are left ?in massive underground bunkers. It's finally time to take back the surface... and yet?, as always,? the worst enemy is not the walkers, but each other. When a new and deadlier Z-Day threatens, will Eden Blake and the other survivors find a way to defeat it-or ??doom ?humanity to extinction?
