We love this Maisie book- it's fun, colourful and full of adventure. My daughter was hooked on the story from the beginning and she loves Maisie's cheeky and adventurous spirit. This is the third Maisie book in our collection, and we can't wait for the next one. We highly recommend this book for all little imaginations!
