Dark Zone (Stephen Coonts' Deep Black, Book 3)

In a secluded headquarters on the other side of the globe a terrorist mission is underway-a plan to set-off an underwater explosion so great, and with such hellish force, that it could shift the very foundation of the earth's surface causing untold calamity and world-wide disaster. The terrorists call it God's Revenge.

A nuclear warhead has gone missing. Small in size, it packs up to ten times the kilotons that exploded over Hiroshima. It's now in the wrong hands, ready to detonate a world war of unfathomable proportions.

In the top secret headquarters of the National Security Agency, a small cadre of special agents form Deep Black, designed to bring a techno edge to covert operations and eliminate the cyber threats to world peace. This is Charlie Dean's world-an NSA ex-marine sniper now enlisted to stop the unthinkable. But when his suspicions of a traitor in his shadow become frighteningly true, Dean's race against time could mean the end of the free world.
