Inspired by the real-life bravery of Catherine Dior, sister of Christian.
Paris, 1944: The war is nearly over, but for members of the Resistance in occupied France, it is more dangerous than ever before. Twenty-five-year-old Gabby Foucher loathes the Nazis, though as the concierge of 10 rue Royale, she does her best to avoid conflict–unlike her bolder sister Yvette, who finds trouble at every turn.
Then they are both recruited into the Resistance by Catherine Dior and swept into a treacherous world of spies, fugitives, and intrigue. While Gabby risks everything for the man she is hiding from the Nazis, Yvette must decide whether to trust an enigmatic diplomat who seems to have guessed her secret. As the threat of betrayal draws ever-closer, one slip could mean the deaths of many, and both sisters must make choices they might regret.
Paris, 1947: Yvette returns from New York to reunite with Gabby and begin life anew as a mannequin for Dior, who is revolutionizing fashion with the New Look. But first she must discover the truth behind Catherine’s terrible fate, while Gabby finds that there are many kinds of courage, and that love is always worth fighting for.
