4.5 stars. What a delight! I absolutely love McClintock's artwork; it really made the book shine. The story is cute, but nothing remarkable--I think it's more a foundation for the glorious artwork (which was, for me, the whole focus of the story). I would have loved this book as a kid because in each time Simon loses something (cat picture, glove, other glove, scarf, hat, sweater) you can find it somewhere in the picture. Also, the tale is set in Paris, which is really neat—Adele and Simon visit art museums, natural history museums, walk by Notre Dame cathedral. Brilliant! :-)
