This searing new novel from bestselling author Whitley Strieber explores the unthinkable but very real possibility: Could terrorists get nuclear weapons?

What would we do if a nuclear weapon were detonated in Washington, D.C., and the U.S. government suddenly disappeared? What would we do if a terrorist organization announced that it had concealed nuclear weapons in every major Western city and then demanded that the entire planet embrace its twisted brand of Muslim fundamentalism?

In Critical Mass, Whitley Strieber explores this unthinkable but real possibility in a furious story that is almost too terrifying to tell. Nuclear interdiction expert James Deutsch and his Muslim wife, Nabila, struggle to stop an impending nuclear attack on a great American city. Along the way, they delve deep into the hidden world of nuclear terrorism and the experts who strive to contain it, and get a compelling look at the titanic battle within Islam over its own future---fundamentalist and rejecting, or compassionate and life-embracing.

Like Strieber's classics Warday and The Coming Global Superstorm, Critical Mass is torn straight from the dark pages of a very dangerous and very possible future.
