THE THREAT IS CLOSING IN

For sale: four nuclear warheads offered to the highest bidder by a rogue Russian general. The buyer: the Sword of Islam, a Mideastern anti-American network. The waring: one by one, they're to be detonated on unknown homeland targets by four separate terrorist cells. Rear Admiral Jake Grafton knows that this could spell doomsday for America.

THE COUNTDOWN BEGINS.
Now, the President of the United States has given Grafton unprecedented authority to do anything he can to stop them. But first, Grafton has to find them. When a traitor infiltrates the cells, the stakes are raised even higher, plunging Grafton into a desperate terrorist hunt. The action swirls from the hot points of central Russia and Suez, to the explosive secrets aboard the mysterious freighter, Olympic Voyager, and finally to the imperiled symbol of American liberty itself. With four disasters set to detonate, it's up to Grafton - and Grafton alone - to annihilate the enemy before the unthinkable becomes a terrifying reality.
