The Small Outsider

I am starting a new book called The Small Outsider by Joan Martin Hundley. I am starting the first chapter today and I already know that the main character has been going through many problems just by looking at the cover. It's a picture of a young child with his hands in his pockets and his shoulders slumped, staring at the ground. I read the summary and it really made me feel upset to know about what the child was facing and the problems that he will meet or have already met on his journey through life. The book is about a boy named David who learns that he has a disorder called autism and how he fights through life.
