The Russian bear is stirring - and it's hungry - in the #1 New York Times'“bestselling series' thrilling fifth novel.

The first disturbing reports reached Delta Force Lieutenant Colonel Charley Castillo in the form of backchannel messages concerning covert U.S. intelligence assets working for a variety of agencies suddenly gone missing and then, suddenly, inexplicably, found dying. Or dead. One in Budapest, Hungary. One in Kiev, Ukraine. One in Ashgabat, Turkmenistan, mere klicks from the Iran border. And then one in Virginia, along the Potomac River, practically in the shadow of CIA headquarters.

Castillo finds the information both infuriating and fascinating, particularly after a recent experience with two CIA traitors whose own deaths were swift and suspicious. Despite there being some similarities, though, he thinks there's something different with these new cases, something he can't quite put his finger on. At first, it's idle thought, but Castillo expects it's only a matter of time before the commander in chief assigns him and his group of troubleshooters in the innocuously named Office of Organizational Analysis to look into the deaths while all those intel agencies fight among themselves trying to put the pieces together.

Meanwhile, Castillo has problems of his own - fallout from recent missions involving a clandestine rescue of a DEA agent from South American drug runners, and the confiscation of some fifty million dollars from thieves in the Iraqi oil-for-food scandal. He's made more than a few enemies, he knows - both foreign and domestic. And then comes another back-channel message, this one delivered personally by his lethal friend, the Russian mobster arms dealer. All that has happened so far, he says, is just a warm-up for what's about to come out of the Kremlin.

Could sabers be rattling for a new Cold War? Or worse? Presidential Agent C. G. Castillo is about to find out. . . .

Filled with Griffin's trademark rich characters and cutting-edge drama, this is another exceptional novel in an exceptional series.
