In love we find out who we want to be. In war we find out who we are. France, 1939 - In the quiet village of Carriveau, Vianne Mauriac says goodbye to her husband, Antoine, as he heads for the Front. She doesn't believe that the Nazis will invade France...but invade they do, in droves of marching soldiers, in caravans of trucks and tanks, in planes that fill the skies and drop bombs upon the innocent. When a German captain requisitions Vianne's home, she and her daughter must live with the enemy or lose everything. Without food or money or hope, as danger escalates all around them, she is forced to make one impossible choice after another to keep her family alive.

The novel begins in 1939, just before the outbreak of World War II, and focuses on the lives of two sisters, Vianne and Isabelle Mauriac, who are from a bourgeois family living in France. Vianne, the older sister, is married to a schoolteacher named Antoine, and they have a daughter named Sophie. Isabelle, on the other hand, is rebellious and passionate and has a troubled past, having been expelled from several boarding schools due to her defiance against authority.

When the Nazis invade France, Vianne’s husband is called up to serve in the army, leaving her to navigate the occupation alone. As Vianne tries to keep her family safe, she is forced to endure the hardships of war. Her home is requisitioned by a German officer, Captain Beck, who moves in with her and her daughter. Vianne attempts to maintain a semblance of normal life for Sophie, grappling with the reality of the Nazi presence and the escalating danger surrounding them.

Meanwhile, Isabelle, who is only nineteen, becomes increasingly disillusioned with the occupation. After witnessing the horrors that the Nazis inflict upon the French people, she decides to join the resistance. Her journey begins when she becomes involved with a group that organizes the escape of Allied airmen from France. Using her intelligence and courage, she helps pilot downed planes evade capture by the Germans, leading them to safety across the border into Spain.

As the war rages on, both sisters undergo profound transformations shaped by their experiences and the choices they make.
