A daring CIA operation threatens chaos in the Kremlin. But can Langley trust the Russian at its center? CIA officers Sia and Max enter Russia under commercial cover to recruit Vladimir Putin's moneyman. Sia works for a London law firm that conceals the wealth of the superrich. Max's family business in Mexico—a CIA front since the 1960s—is a farm that breeds high-end racehorses. They pose as a couple to target Vadim, Putin's private banker, and his wife, Anna, who—unbeknownst to CIA—is a Russian intelligence officer under deep cover at the bank. As they descend further into a Russian world dripping with luxury and rife with gangland violence, Sia and Max's only hope may be Anna, who is playing a game of her own. Careening between the horse ranch in northern Mexico, the corridors of Langley, and the dark opulence of Putin's Russia, Moscow X is both a gripping thriller of modern espionage and a raw, unsparing commentary on the nature of truth, loyalty, and vengeance amid the shadow war between the United States and Russia.
