It’s hard to call this a celebrity author or a celebrity picture because it’s the song by a singer put in picture of a format. It’s fine. The song was a hit for multiple years with the Happy Feet movie and yes this book was checked out like crazy. Is there still place for it? Yes… but I have a feeling this is one that when Library copies fall apart, they will not be replaced. I do like that they use real pictures in the book that are set to a theme, and it all goes well together. And I think my favorite thing of this book is the letter from Pharrell to the kids in the back. I think Pharrell should try to really write a picture book instead of just putting his songs in page format.
