"When the Nazis march into Paris, an American woman uses her bookstore to aid the resistance, while a businessman chooses to sell his products to Germany-and send vital information home to the US. Can they work together for the higher good, or will it cost them everything they love?"-- Provided by publisher.

As the Nazis march toward Paris in 1940, American ballerina Lucie Girard buys her favorite English-language bookstore to allow the Jewish owners to escape. She struggles to run Green Leaf Books due to oppressive German laws and harsh conditions, but finds a way to aid the resistance by passing secret messages between the pages of her books. Widower Paul Aubrey wants nothing more than to return to the States with his little girl, but the US Army convinces him to keep his factory running and obtain military information from his German customers. As the war rages on, Paul offers his own resistance by sabotaging his product and hiding British airmen in his factory. After meeting in the bookstore, Lucie discovers he sells to the Germans. For Paul to win her trust would mean betraying his mission. -- adapted from back cover
