The Unwatched Door

The asteroid Apophis is going to hit Earth.
Colby Chambers proves it.

The evidence says he concealed the danger. Then the case against him grows darker: he may have done more than hide what was coming.

He may have helped cause it.

Altered records, messages, financial trails, foreign contacts—months of evidence add up to a secret life he knows he never lived.

Then Colby learns an anonymous source is already telling the public Apophis will hit Earth—before officials announce it. The source backs the claim with information no outsider should possess.

With the impact clock running down, Colby is pulled back into the effort to stop Apophis. The team still needs his judgment, even while he remains under investigation. He must help save a world that increasingly believes he put it in danger.

But someone is using the crisis for something larger. While the world watches Apophis, Colby begins to realize the asteroid may not be the only threat.
