Virulent pockets of plague, first reported in China, break out worldwide and spread with mind-boggling speed. CIA black ops agent Chad Halverson flies to Los Angeles to visit his brother after receiving a call that his brother has been hospitalized after a car accident. Halverson's Boeing 737 crash-lands in an eerie Los Angeles shrouded with an impenetrable haze of smog. But that is only the tip of the iceberg of Halverson's nightmare. Lurking in this mist are legions of plague-infected living dead who are driven by an all-consuming lust for human flesh. Halverson's reunion with his brother must take second place to his own struggle to stay alive.
As civilization crumbles into chaos, it will take all the skills and wits Halverson and his fellow passengers possess for their hunted party to survive in a world overrun with hordes of flesh-craving zombies.
Which will pose a bigger threat to Halverson and his ever-dwindling band--their own bickering as they try to organize and defend themselves, their enemies the living dead, or the new "civilization" of men that is superseding the old?
Cassiday pits a heroic Texan pilot, a CIA agent, an arrogant banker, a preachy minister, a whiny call girl, and ordinary folks against zombie hordes that have overrun smog-engulfed Los Angeles. As civilization crumbles and the slaughter escalates, one character wonders, "Is this madness really happening?" The superabundant gore carries implications of human-zombie moral equivalence, a notion extended by the crucifixion of zombies. Character-ization throughout is as weak as a zombie's dignity, and the subplot of disputes over leadership and the best course of action yields predictable results. "I can't take much more of this," one character moans, but she has no choice.
