Furnace: Execution by Alexander Gordon Smith (author) (UK edition)

“The whole world has become a prison, and Alfred Furnace is its master. Monsters rule the streets, beasts of pure fury that leave murder and madness in their wake. Those who do not die become slaves to Furnace’s reign of cruelty. I am a monster too. I am the only one who can stop him, but in doing so I risk becoming the force that kills us all. Am I the executed or the executioner? Who will die? Me, Furnace or the entire human race? All I know is that one way or another, it all ends today.”
