Budding billionaire Greg Kenton has a knack for making money and a serious rival. When he issues his first Chunky Comic Book at the beginning of sixth grade, his neighbor and classmate Maura Shaw produces an alternative. Their quarrel draws the attention of the principal, who bans comics from the school. But when they notice all the other commercial messages in their school, they take their cause to the local school committee. Without belaboring his point, Clements takes on product placement in schools and the need for wealth. “Most people can only use one bathroom at a time,” says Greg’s math teacher, Mr. Z. Greg gets the message; middle-grade readers may ignore it in favor of the delightful spectacle of Greg’s ultimate economic success, a pleasing result for the effort this up-and-coming young businessman puts into his work. Clements weaves intriguing information about comic book illustration into this entertaining, smoothly written story. Selznick’s accompanying black-and-white drawings have the appearance of sketches Greg might have made himself. This hits the jackpot. (Fiction. 9-12)
