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.
