Paris, 1939: Young and ambitious Odile Souchet has it all: her handsome police officer beau and a dream job at the American Library in Paris. When the Nazis march into Paris, Odile stands to lose everything she holds dear, including her beloved library. Together with her fellow librarians, Odile joins the Resistance with the best weapons she has: books. But when the war finally ends, instead of freedom, Odile tastes the bitter sting of unspeakable betrayal.
