Robert Ludlum's The Bourne Dominion (Jason Bourne, Bk. 9)

Jason Bourne is searching for an elusive cadre of terrorists planning to destroy America's most strategic natural resources-and needs the help of his longtime friend, General Boris Karpov. Karpov, the newly appointed head of Russia's most feared spy agency, FSB-2, is one of the most determined, honorable, and justice-hungry men that Bourne knows. But Karpov has made a deal with the devil. In order to remain the head of FSB-2, he must hunt down and kill Bourne.

Now, these two trusted friends are on a deadly collision course. From the Colombian highlands to Munich, Cadiz, and Damascus, the clock is counting down to a disaster that will cripple America's economic and military future. Only Bourne and Karpov have a chance to avert the catastrophe-but if they destroy each other first, that chance will be gone forever.
