Forty days have passed since the end of the world began. Billions of people were killed in less than half a day and now the entire world is rotting. Everything is disintegrating ... Survivors are few and far between in this deadly environment, and those who are still alive are forced to deal with a nightmare situation: the scale of the devastation is unprecedented. The shadowy landscape is swarming with the dead, their decaying bodies deteriorating day by day. Limited by their appalling physical condition, the only emotions they are able to display are anger, rage and hate and yet, remarkably, they are becoming more controlled. They are becoming self-aware, and they will defend themselves at all costs. A group of eleven men and woman have managed to survive against the odds, protected by the geography of the land and sheltering in a derelict block of flats. They have been surrounded for weeks, but they have always been in control. Until now. For the bodies are advancing. The situation is changing.
