Heidi's brother, Donald, is 16 and Autistic. She has always loved playing with him, but now she's 11 and her life is changing. She's embarrassed to have her brother around and tries not to tell anyone about him. High school boys bully him. When the kids at her school find out about him, she gets bullied too.

It's not fair. No one seems to understand.

But Heidi needs to understand too. She can't change her brother, but she can change how she feels about him, and she can get people to see why her brother is special.
