Thirty years ago, in a facility buried beneath a vast Wyoming emptiness, an experiment gone awry accidentally opened a door.

It is the world's best-kept secret—and its most terrifying.

Trying to regain his life in the Alaskan wilds, ex-con/ex-cop Travis Chase stumbles upon an impossible scene: a crashed 747 passenger jet filled with the murdered dead, including the wife of the President of the United States. Though a nightmare of monumental proportions, it pales before the terror to come, as Chase is dragged into a battle for the future that revolves around an amazing artifact.

Allied with a beautiful covert operative whose life he saved, Chase must now play the role he's been destined for—a pawn of incomprehensible forces or humankind's final hope—as the race toward Apocalypse begins in earnest.

Because something is loose in the world.

And doomsday is not only possible . . . it is inevitable.
