Harry and Willy and Carrothead (1991)
Harry was born with no left hand, and is fitted for a prosthesis. When he attends school, he makes new friends with Oscar, who is sometimes called Carrothead and hates it. Prejudice and baseball and especially friendship are the simple themes of the book. I interviewed a wonderful man who made prosthetics for children.
