Fortress — Michael L. Brown

The world has changed, not from terrorist threat or attack, but from an unforeseen enemy, the undead. Now the remnants of humanity are living barricaded from the world and battling to not only reclaim the world from the zombies, but survive the mobile human threat and the day-to-day struggles of life, love, and the re-birth of society. Follow our fellow humans through the maze of human relations in a closed society, the fanaticism of zombie worship and the dark side of the human condition.
