I loved this book! I think kids nine and up, will understand the moral of the story and understand all the messages this book sends to us. What parents should know is that George is judged for trying to show who he is and is punched in the stomach a.k.a bullies! George also has a stash of Seventeen magazines that she holds onto because she considers the girls (models) of the magazine her friends. People also thought George was gay but George isn't so sure. George wonders about having a surgery he has heard about that completely turn him physically into a girl. Another thing is sometimes the book references to mild sexual topics. But that is why I caution for kids 10 and up to read this book. Overall, what the book is about is George is technically a boy, but on the inside she feels more like a girl. The fourth grade puts on the production Charlotte's Web, George really wants to play the spider, Charlotte. But she's not sure if he can because everyone sees her as a boy! I'm not going to spoil the rest. The great message is that George starts to follow the path to her true self. Which is the best path to take. George discovers she doesn't need to change for people to accept her, or at least she shouldn't have to. George sees herself as a girl, so she wants people to see her as a girl. There is nothing wrong with how she feels. She is being her true self. That is the best thing she could ever be.
