THE WONDER WORM WARS

When Palatini (Moosetache, p. 386, etc.) allows the nine- year-old narrator, Elliot, to get past his penchant for name- calling and his smart-aleck, center-of-the-universe attitude, readers will find a good story in the offing, about boy-girl role reversal. While his sister has a new baby, Elliot finds himself in charge of his nephew, Jonathan, a squirmy, impetuous preschooler. To make matters worse, Elliot breaks his arm and can't participate in the usual ball games and swim meets with best friend, Goog. Enter Corrine, the new girl with a baseball- wallpapered room who effortlessly replaces Elliot on both teams and in the neighborhood while he struggles through a summer of smelly diapers and baby burps. Palatini is least effective when she employs sarcasm and too-hip dialogue, but perfectly at home evoking scenes of family warmth and camaraderie. (Fiction. 8-11)
