What metaphors are used in Suite Francaise by Irene Nemirovsky?

Paris is a metaphor for love and the danger of impending war. The novel begins in the city of Paris, France, where the people are having a difficult time believing the war will reach them. They have been enduring air raids, blackouts and the distant noise of bombs, but when their beautiful city begins to be bombed, swarms of Parisians begin an exodus to the countryside in cars, on foot, on trains and bicycles. Paris and its outlying towns, farms and villages are the primary locations in the novel.
