Full disclosure: the author sent me a link for a free download of the book which resulted from my entering (but not winning) a FirstReads copy on Goodreads.com. This was done in exchange for my promise to review the book.
That being said, it was a book that was worth paying for! I read it to my 5-year old, and the illustrations, although very basic, tell the story very well and teach the lesson that diversity enhances each of our lives. I asked her, at the end, if she "loved it" or if she "really liked it", and she said the latter (resulting in the 4 stars).
