After losing everyone she loves in the final days of World War II, Ingrid Bauer agrees to a hasty marriage with a gentle Soviet embassy worker and follows him home to Moscow. But nothing deep within the Soviet Union’s totalitarian regime is what it seems, including her new husband, whom Ingrid suspects works for the KGB. Upon her daughter’s birth, Ingrid risks everything and reaches out in hope to the one country she understands and trusts—Britain, the country of her mother’s birth—and starts passing along intelligence to MI6, navigating a world of secrets and lies, light and shadow.

Washington, DC, 1980

When the KGB murders her bestfriend, Anya picks sides and contacts the CIA. Working in a military research lab, Anya passes along Soviet military plans and schematics in an effort to end the 1980s arms race.
