I suppose that beginning the review for a children's book by stating that it's perfect for when you're stuck outside your hotel room, waiting for your baby to wake up crying (again), and need something to distract you is not all that useful. Demographically speaking.
Although I will say that this is one of those kids books that is just as enjoyable for adults with its cleverness. And it's kind. I've said this about Ursula's work before, but her goal seems to be to fill the world with brave, kind and, above all, practical heroines who do what needs to be done. Usually with a sigh and a bit of sarcasm. I have never met a main character of hers I did not adore and Molly is no exception.
Also, Pins and the goldfish. I didn't get the reference to Ursula's art until the mention of Pins' backstory, but that was amazing!!!
