A slick, slangy, sportswriter style, with occasional lapses into very poor grammar, eventually carries the message that school and a career designing powerful automobile engines have greater appeal than a few flash-in-the-pan wins on the California roadster and sports car racing circuit. These can give a passing glory and end in a life with little to show for the effort. Damaging other people's property, general dishonesty, and lying to his physician father seem to reward Cotton Clark, a high school senior with considerable mechanical ability. The very lack of punishment for his behavior seems to instill greater maturity and a sense of responsibility so that he becomes an admirable character by the end of the story. Improbable? Yes. Appealing to the hot rodder? Yes. Good book? No.
