Ironman

Crutcher reassembles some of the character types he used to riveting effect in his stellar Staying Fat for Sarah Byrnes: a teenage misfit narrator enduring grueling athletic training; a tough heroine with a tragic past; a right-wing authoritarian heavy; enlightened teachers; and a sadistic father. At its best, the narrative crackles along in the author's inimitable style. Beauregard Brewster, a would-be Ironman triathlete, chronicles the events that ensue after he insults an oppressive teacher and is forced to take an anger-management class with other troubled students. But Crutcher's message sometimes overwhelms the cast and the story line. Beau's stern father, who has to be right at all costs-even if it means stacking the deck against his son-is one of the few fully fleshed-out characters. Many are either saintly multiculturalists (Beau's gay swimming coach, earlier met in Stotan; ``Mr. Nak'' the Japanese cowboy anger-management teacher; the black female high school principal) or, in the case of the offensive teacher, outright villains. In spite of these flaws, Crutcher achieves many memorable moments-exchanges between the students in the anger-management class, for example, are idealized but often deeply moving. Ages 12-up. (Apr.)
