You should have seen the look on my daughter's face when I picked this book up and said we were going to read it together -- it said "yeah, right....that's huge" I had been wanting to read this myself, and when I insisted (and showed her how many of the pages were actually illustrations) she relented.
I thought the format of the book was just lovely. The illustrations really added a depth to the story, in places showing things not actually in the text.
I found the story bittersweet and the Parisian 1930's setting intriguing. Maya and I would finish a couple of chapters before bed and she would complain, "You can't stop there....we have to find out what happens next....that's an awful place to stop!" Of course I would see that there were only a few pages of actual text in the next chapter, give in and read that chapter only to hear, "No, you can't stop there either!"
I love when she has to admit I picked out a great book!
