Captain Dominika Egorova of the Russian Intelligence Service has returned to Moscow. She despises the men she serves, the oligarchs, crooks and thugs of Putin's Russia. What no one knows is that Dominika works for the CIA as Washington's most sensitive penetration of the Kremlin. As she dodges exposure, Dominika faces a murderously psychotic boss, assassination attempts and counter-intelligence ambushes, and must rescue a compromised agent. Complicating it all is Dominika's relationship with her CIA handler, Nate Nash. And when a mole in Moscow finds her name on a classified list of sources, it is a virtual death sentence.
