My four-year old daughter received this book as one of her Christmas gifts, and enjoys it. We purchased the book to go along with a couple of Mariposa figurines she also received. After reading the book I felt like we needed to watch the movie to make everything a little clearer. I understand that it's hard to fit a complete movie into a child's book, but I would say that the goal age for this book should be about six, depending of the focus-level of your child. Overall, we're happy with the purchase and will continue to read this for years to come.
