And now, 25 years later, Sarah's key moves me. (yes, I'm late for the party.) It's a story of a girl in war time Paris and of a woman also in Paris in the present. It's about the French's (not just the Nazis) part in the round up of the Jews -- the Vel d'Hiv Round up and of a journalist's life transforming experience in discovering her story.Like many successful novels, there is a movie apparently. I'll have to check it out.
