I have very mixed feelings on this book. I know that there are things that happen to your body when you sleep, but not sure I wanted it described to my Granddaughter the way it was. On good side it taught not to give up and to keep trying no matter what your task is. I really liked the illustrations of Puck and Lola. I received this ebook free and don’t know if i would have gotten it otherwise. My Granddaughter liked it as she likes all things with fairies.
