Out of my mind

Out of my mind is a book i am reading so far it is great but sad at the same time. I am only on chapter 3. Its about a eleven year old girl named Melody( i like that name) , she cant move her arms, and legs so she is stuck in a wheel chair. She is really smart but no one knows (not even her teacher and her doctors don't think she is capable to learn), she remembers everything. But she cant speak.
