Finally, some 11-year-olds you'd really want to hang with. Mary Ellen Bobowick and her best friend, Justine Kelly, are smart and sophisticated preteens. Eating Chinese food one night—with chopsticks, of course—Mary Ellen gets a fortune cookie that warns of bad luck to come. The youngster, who wants to be a biologist like her mother, has a scientific mind and scoffs at the dire prediction. But when a stream of misfortune comes her way, she begins to wonder if the cookie hadn't had a point. First she breaks the mirror in Dr. Bobowick's great-grandmother's antique silver mirror-and-brush set. Then she discovers that Justine is moving to France for a year, fights with Justine, drops a jar of Career Day fruit flies in her classroom, and gets sprayed by a skunk! And that's only part of it. But eventually things look up for Mary Ellen—in the form of her handsome classmate Ben, as she confides in best pen pal, Justine—and she discovers that all the bad luck was simple, scientific cause-and-effect, nothing more.
