I usually have a “no Nazis” rule for fiction, but it came up against my “always read the books about librarians” rule. This book was actually a bit more about the French resistance character and it was stronger for it. There are two main characters in it and you watch their story arcs bend towards one another. That said there are a LOT of Nazis and if I was going to do it over, I might not have read this even though I enjoyed it. Decent historical fiction.
