She cannot take her baby daughter *Mathilde* (2 years old) with her on the run.
In a desperate choice, she entrusts Mathilde to Juliette. Juliette promises: "I will love her as my own. One mother to another."
Juliette now has four small children in the apartment above the bookstore: her three - *Emma, Theo, and baby Lucie* - plus Mathilde. Mathilde and Lucie are best friends, like their mothers.
*1943 - The Bomb:*
Nowhere is safe, not even a quiet bookshop. During an Allied bombing raid on Paris, a bomb falls directly on Juliette's neighborhood. The bookstore and apartment are destroyed.
Elise, hiding in the countryside, hears the news after the Liberation. She rushes back to Paris in *1945*.
She finds rubble. The shop is gone.
She learns that Juliette and *one child* survived: baby Lucie. Juliette's husband Paul, her two older children Emma and Theo, and - she is told - little Mathilde, were killed in the bombing.
