Eva is 23, a Jewish graduate student at the Sorbonne in Paris. After her father, a Polish Jew, is arrested in a roundup, Eva and her mother *Mamusia* must flee Paris for the Free Zone (Vichy France).
Eva discovers she has a talent: *forgery*. She can perfectly forge identity documents, birth certificates, and baptism papers that hide someone's Jewish identity.
They find refuge in the tiny mountain town of *Aurignon* (Aurignon is fictional, based on real towns).
There, a Catholic priest, *Père Clément*, recruits her into the *French Resistance*. She works with a handsome young forger, *Rémy Duchamp*.
Together, Eva and Rémy forge hundreds of documents for Jewish families, especially *children*, to help them escape over the mountains to neutral Switzerland.
But Eva has a heartbreak: If she erases a child's real name and gives them a new French name to save their life, what if that child is so young they forget who they really are? Their identity will be lost forever.
