Have you read "My Life in France" yet? It's so darned entertaining. I actually listened to the book on CD during a road trip to the Great Smoky Mountains a couple of years ago. The whole family got a big charge out of Julia discovering her calling and her endearingly goofy phrases.
I got to meet this legendary cooking icon and she was so warm, so engaging. She had the gift of natural curiousity and conversation. Maybe that's why she was chosen to be a spy!
