Book Recommendation

My book so far includes The main character Melody. And the genre is either realistic fiction or non-fiction. You can't tell in any way because there is no proof either way. The Characterization of the other characters is full, but extremely limited because Melody is disabled. As the reader, you can't see inside anybody else's head aside from Melody's, and this makes characterization much harder to understand, because characters are only able to be characterized from what Melody sees, which is a dumbed down kiddie version of what's really happening.
I think that the book is well written, and that the author did a good job of displaying Melody and her interactions with other characters, because it's hard to show what a special needs child is thinking at all times. Melody is a very thoughtful character who has feelings and emotions, but those are never shown to the other characters at any time.
I would give this book a four out of five, the four stars are because she did such a good job of addressing the topic, the missing star is because this book is very short, and I think that's because the author leaves holes in the story where Melody's life is taking place. There are so many things that Melody experiences that the reader can't see because it is in the parts of Melody's life that the writer doesn't show.
