But Madriani has been linked to the murder of a Washington, D.C., political staffer, and authorities believe a shadowy figure called Liquida - a hired assassin known as "the Mexicutioner" - may be responsible. And this man, as the last survivor of the attack in San Diego, might be driven by a bizarre and horrifying star-crossed vendetta, and might now be looking for Madriani himself. What Madriani and Cole begin to fear is that the Old Weatherman and this madman have joined forces and intend to pull the city - and the country - into a vortex of terror before Madriani and Cole can find answers to the enigma that is "the rule of nine."

Newly elected in his own right, Jack Ryan has found that being President has gotten no easier: domestic pitfalls await him at every turn; there's a revolution in Liberia; the Asian economy is going down the tubes; and now, in Moscow, someone may have tried to take out the chairman of the SVR--the former KGB--with a rocket-propelled grenade. Things are unstable enough in Russia without high-level assassination, but even more disturbing may be the identities of the potential assassins. Were they political enemies, the Russian Mafia, or disaffected former KGB? Or, Ryan wonders, is something far more dangerous at work here?

Ryan is right. For even while he dispatches his most trusted eyes and ears, including black ops specialist John Clark, to find out the truth of the matter, forces in China are moving ahead with a plan of truly audacious proportions. If they succeed, the world as we know it will never look the same. If they fail...the consequences will be unspeakable.

Blending the exceptional realism and authenticity that are his hallmarks with intricate plotting, razor-sharp suspense, and a remarkable cast of characters, this is Clancy at his best--and there is none better.
