The world has been devastated by an epidemic. Although there are pockets of an attempted continuation of civilisation, the truth is that the world has gone to hell in a handcart. The reason for this is a disease that has wiped out most of the world's population. It kills almost all those who are not of the blood group 'O neg'. Those people who survive are untouched. Everyone else dies. Infrastructures have collapsed. Mobs run rampant. The only kind of law that exists is that imposed by the people with the biggest guns. In this devastated and chaotic world who can bring hope and order? It's never easy being fifteen, but when your teachers are killing each other, the prefect who loves to bully you is experimenting with crucifixion, and the rival gang from across town have decided that ritualistic cannibalism is the way to go, spots and body-odour don't seem like such big problems after all. These are the final days of St Marks School For Boys, and the punishment for disobedience is death!
