Though portrayals of bullying in children's books stretch back to Victorian public school stories, this article sees a new subgenre about bullying in young adult novels emerging in the post-Columbine years. Selected works by Jerry Spinelli, Walter Dean Myers, Jaime Adoff, Carol Plum-Ucci and Rita Williams-Garcia are examined, although the article begins by looking at a precursor of this subgenre, Robert Cormier's classic "The Chocolate War." In this subgenre, it is argued that bullying is not presented as dysfunctional adolescent behavior, but as a tool for addressing issues of difference and discrimination on the grounds of race, class, sexual orientation or personality; issues that filter into adolescent culture. High schools are thus portrayed as totalitarian microcosms where bullying functions as a means of social control, curbing deviance from masculine, heterosexual, middle-class and white norms. The narrative techniques and themes of these books--around homophobia, jock culture, rampage shootings and girl-on-girl violence--will be examined.
