This is a neat idea, or slick marketing. This book is meant to be part of a set with a plushie and a blankie. By the time you buy into the whole set you have spent a not insignificant amount of money. But when you are kid, having things go together feels good. This works with that. The book is okay, not amazing, so value is bringing all the pieces together. The book is also a little different in that it includes some extra non-story pages at the end including a recipe for Unicorn CheckMix of all things.So, if you have a person in your life that is in their Unicorn phase, this may be a good fit for you.
