"Vienna, 1954: 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 within the Soviet Union's totalitarian regime is what it seems, including her new husband, whom Ingrid suspects works for the KGB. Inspired by 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. She begins passing intelligence to MI6, navigating a world of secrets and lies, light and shadow. Moscow, 1980: A student in the Foreign Studies Initiative, Anya Kadinova finishes her degree at Georgetown University and boards a flight home to Moscow, leaving behind the man she loves and a country she's grown to respect. Though raised by dedicated and loyal Soviet parents, Anya soon questions an increasingly oppressive and paranoid regime at the height of the Cold War. Then the KGB murders her best friend and Anya chooses her side. Working in a military research lab, she relays Soviet plans and schematics to the CIA in an effort to end the 1980s arms race. The past catches up to the present when an unprecedented act of treachery threatens all agents operating within Eastern Europe, and both Ingrid and Anya find themselves in a race for their lives against time and the KGB."-- Provided by publisher.
