It is seven months since the outbreak. In the anarchy and chaos that came with the undead, civilisation was destroyed. In the wars that followed, the planet was nearly ruined. Billions died. Only a few thousand survived.

Fifty people have found refuge in the Tower of London. Zombies plague the city outside the old fortress. The wasteland beyond is filled with nothing but radioactive ruins. With nowhere left to retreat to, and in a final attempt to make the ancient castle a place where they can do more than just slowly starve, the survivors search for food in the abandoned coastal farms. They find something else. They discover that hunger, thirst, and the undead aren't the only threat they face.

Betrayal and danger lurk in the shadows in this, the penultimate book in the series. It will conclude in Book 7: Home.
