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? Cade didn't exactly care about people, but one of the people he most cared about was in trouble and he'd help out if he could. If that meant heading down to San Francisco - even though nobody ever came back from there alive - well, fine. This ain't a peaceful story and Cade...Cade isn't a peaceful man.
