As the threat of World War II looms in the distance, a rare and heroic woman uses the 1936 Berlin Olympics to bluff her way behind enemy lines, bringing the truth into focus and coaxing hope from the shadows.

With the world's eyes on a rising German power, the English aristocracy turns to an age-old institution to stave off war and strengthen political bonds-marriage. Debutantes flock to Germany, including Lady Viviane Alden. Sent to chaperone her sister during the 1936 Berlin Olympics, Viviane's true purpose is more clandestine. While many in England want to appease Hitler, others seek to prove Germany is rearming. But they need evidence, photographs to tell the tale, and Viviane is a genius with her trusty Leica. Who would suspect a pretty, young tourist taking holiday snaps of being a spy?

Viviane expects to find aggression and belligerence, but during the Olympics, Germany doesn't appear to be the violent, anti-Semitic country it's been reported to be. But first impressions can be deceiving, and it's up to Viviane and the journalist she's paired with-a daring man with a guarded heart-to reveal the truth.

But others have their own reasons for befriending Viviane, and her adventure takes a darker turn. Suddenly Viviane finds herself caught in a web of her own deadly games-and closer than she ever imagined to the brink of war.
