Firestorm! A mole has infiltrated Ironwood National Laboratory in Los Alamos, New Mexico, a top-secret research center for the development of high-tech and nuclear weaponry. Someone is about to commit the foulest, most catastrophic brand of treason — and one man must prevent it: CTU agent Jack Bauer. Caught in the crossfire between two rival criminal operations, each intent on controlling the terrifying machinery of Apocalypse, the rogue anti-terrorism operative has twenty-four hours to forestall America's worst nightmare. As a devastating wildfire ravages the countryside, each ticking second brings Jack closer to the explosive confrontation that will ultimately seal his nation's fate: a lethal battle with the world's most efficient killer, Annihilax, the Death Angel.
