Henry spent eight years chained to a post. Exposed, starved, infected with the December Plague, and mad. During those eight years, the December Plague consumed most of the world's human population, causing the infected to become violent and cannibalistic. But Henry escaped. And now he's been cured. He vividly remembers what has been done to him and others. He can also recall the terrible things he did while he was infected. He and his fellow survivors face a world unlike anything they knew before. They are weak, lost and completely alone. Now released from both the madness of the Plague and the cruelty of their captors, they must decide which is more important : survival or revenge.
