In less than twenty-four hours, in a palatial hideaway in the mountains of Colorado, a group of America's most powerful industrialists will be gathering for their annual summit. The bizarre disappearance of all the members of a local crackpot cult—and of two ATF agents assigned to keep an eye on them—may have no connection whatsoever to the impending high-powered conference. But with so many corporate titans grouped together in one location, CTU can't afford to take chances.

Sent to investigate, Jack Bauer is immediately plunged into a maelstrom of treachery, terror, and slaughter as he uncovers clues to a devastating conspiracy that could leave America's most essential institutions in ruins. And now the rogue CTU operative has only hours to prevent the unthinkable—before the relentlessly approaching storm of blood and fire rocks his nation to its foundations.
