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? Jasmine has spent five years underground, locked in a secret government bunker with no one but the skeletons of her colleagues for company. Outside, the world has gone to hell, a mysterious virus killing all but one in 20 of the world's population. It's enough to drive anyone mad - but Jasmine's crazier than most. The cure she was working on had an unexpected side effect: psychotic symptoms which only the most powerful drugs can suppress. Jasmine's quest to find a cure draws her across the fractured continent of America and into the darkest recesses of her past.
