Ema the Rhinoceros Book

This book might be a good starting point for introducing youngsters to the period of U.S. history in which the government forced Japanese-American families into so-called internment camps after Pearl Harbor, even though there's no concrete sense of historical facts in the story, such as how long the family was confined or the condition of their house after they were allowed to return it.

Other discussions might arise from the text, I would hope, such as the acceptance the boy is afforded only after he becomes a better ballplayer. For the same age group, there's also Barbed Wire Baseball.
