It's late 1987 and American CIA operatives in the Soviet Union are dying. One by one, case officers fall ill and perish, all exhibiting the same frightening symptoms: weakness, vomiting, hair loss, hemorrhage, death. Eventually, the cause of death becomes clear: assassination by radiation poisoning. Somehow, the KGB has learned the identities of American operatives and are eliminating them. Without knowing the source of the leak and who has been compromised, CIA Director Aaron Stallings has little choice but to utilize his most secret weapon, his blackest of black ops agents, Tracie Tanner. Her assignment: Travel to Moscow. Identify the men murdering Americans. Stop the killers by any means necessary. Her assignment is straightforward and nearly impossible. And if it doesn't kill her, it may just change her forever.
