What I loved: This is quite the imaginative story, and there are a lot of interesting details in the book. Perhaps the most interesting is the context at the end about who the singer, Edith Piaf, and Josephine were and their roles in history. They are much more than what we see in their brief interludes in the book.
What left me wanting more: I would have liked more about these historical figures and more than their performing to be in the book, perhaps with a nod to their wartime contributions. I think the story could have been expanded to include more, but it really only presents them as entertainers. As a small point, the story also reads a bit awkwardly in places.
Final verdict: PARIS CAT is an imaginative picture book about a cat who finds a place in entertainment. The historical context at the end is intriguing and could spark an additional lesson in these interesting individuals.
