Colin was adopted by a white family. They love him and treat him as one of their own.
Scholastic sent me an ARC to read for review (thank you). It has been published and you can get a copy now.
He knows he's different from the rest of his family, but he likes that. He is his own individual.
A school they are told to draw a picture of their family. He does but he colors himself brown. When they show their pictures to the class, he gets some criticism from other schoolmates for being different. He explains why he likes that, and other classmates stand with him.
As long as you are loved, it doesn't matter what you look like. Be your own unique self and enjoy life!
