"CLANCY STiLL REIGNS."
- THE WASHINGTON POST

Number-one New York Times - bestselling author TOM CLANCY returns with an electrifying work of fiction that may soon be frighteningly close to reality....

For the covert warriors of the secret organization known as The Campus, the fight against America's enemies is never over - if only because one enemy's destruction inevitably gives rise to a new, even more dangerous foe.  But for Jack Ryan, Jr., and his comrades, the danger has just hit home in a way they never expected.

The Campus has been discovered.  And whoever knows it exists knows it can be destroyed.

Meanwhile, President Jack Ryan has been swept back into the Oval Office - and his wisdom and courage are needed more desperately than ever.  Internal political and economic strife has pushed the leadership of China to the edge of disaster.  And those who wish to consolidate their power are using the opportunity to strike at long-desired Taiwan and at the Americans who have protected the island nation from China's depredations.

Now, as two superpowers move ever closer to a final confrontation, President Ryan must use the only wild card he has left - The Campus.  But with their existence about to be revealed, its members may not even have a chance to enter the battle before the world is consumed by war.

In Threat Vector, Tom Clancy once again proves his absolute command of military action and international intrigue with a thriller that will have readers turning the pages - and turning in their sleep.

Back flap:

Thirty years ago, TOM CLANCY was a Maryland insurance broker with a passion for naval history.  Years before, he had been an English major at Baltimore's Loyola College and had always dreamed of writing a novel.  His first effort, The Hunt for Red October, sold briskly as a result of rave reviews, then catapulted onto the New York Times bestseller list after President Reagan pronounced it "the perfect yarn."  Since then Clancy has established himself as an undisputed master at blending exceptional realism and authenticity, intricate plotting, and razor-sharp suspense.

MARK GREANEY has a degree in international relations and political science and is pursuing his master's in intelligence studies with a concentration in criminal intelligence.  He is the author of The Gray Man, On Target, and Ballistic.  In his research for these novels, he traveled to seven countries and trained alongside military and law enforcement in the use of firearms, battlefield medicine, and close-range combat tactics.
