Having completed her mission to silence an agency defector, CIA operative Cassie Bradbury finds herself cut adrift in Moscow with no documents, no tickets and no identification. Hot on her trail are the Kremlin, the Russian Mafia - and Sean Ravensdale, the disgraced ex-CIA agent who has been sent to track her down. Realizing that she has been set up and is now expendable, Cassie will need all her courage and resourcefulness to outwit her pursuers - and stay alive long enough to exact revenge on the man who recruited her, who trained her - who betrayed her.
