When Russian president Maxim Krupin discovers that he has inoperable brain cancer, he's determined to cling to power. His first task is to kill or imprison any of his countrymen who can threaten him. Soon, though, his illness becomes serious enough to require a more dramatic diversion-war with the West. Upon learning of Krupin's condition, CIA director Irene Kennedy understands that the US is facing an opponent who has nothing to lose. The only way to avoid a confrontation that could leave millions dead is to send Mitch Rapp to Russia under impossibly dangerous orders. With the Kremlin's entire security apparatus hunting him, he must find and kill a man many have deemed the most powerful in the world.
