Book excerpt: Of all the things there were to do on Saturday mornings in the park, playing baseball was what Joe wanted most to do that day. He found a game going, and asked if he could play. "Scram kid," said one of the boys. And then began Joe's angry, wide-awake dream. Each time he tried to get into the game and couldn't, he pictured himself getting even by yelling back at them twice as hard and by being twice as mean.
