It beats me how people can keep secrets for years, in this case, over sixty years.  Although I realize that I have never suffered trauma, like Eva did in The Book of Lost Names by Hanna Harmel.

The setting is France in WWII.  Eva is Jewish.  When France was first invaded by Germany, there was a section of France that people felt safe, called the Free Zone.  Gradually, that was not so, but in the beginning of the story, we see Eva's father picked up by the Gestapo.  Eva and her mother run to the Free Zone.  Eva's mother proves to be a pain in the a$$.  

The mother wouldn't leave their Paris apartment: what if their father came home and couldn't find them, where are we going, we don't know anyone there, etc.  

Eva worked for the resistance by forging documents.  However, the work was inside a Catholic Church.  The leader was a Catholic priest.  Eva falls in love with a Catholic.

As you can imagine, the mother complained the entire time. Poor Eva was torn between saving Jews and her mother.  Fortunately, the mother lost and Eva continued her work. As the war progressed, their town and the Free Zone wasn't safe.  They had to escape to Switzerland.

The title of the book, The Book of Last Names, comes from Eva's code.  In an old Catholic book, Eva put the true names of the people, whose names she changed in a code.  The ending of book has Eva responding to advertisement, looking for the book's owner.  Eva responds and she is united with the book.

I learned about forging as resistance, in this story.  It saved many lives.
