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 1 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 for this new plague, as well as for her own barely suppressed madness, draws her across the fractured continent of America and into the darkest recesses of her own past.
