Thanks to her great mop of flaming-red hair and some unfortunate incidents on the first day, Theodosia “Bunny” Baxter’s hopes of invisibly blending in at her new middle school may be dashed. But the ensuing notoriety leaves her alternative scheme—being expelled, so she can go to school with her best friend—all the more doable. Or so she thinks. As it turns out, she’s not very good at bad behavior, among the many endearing qualities that will draw readers to her. Bunny fumbles her way toward successfully coping with many things, including bullying, pressure to sign up for an athletic competition, complex feelings about being adopted, and anxiety attacks that manifest in part as serious rashes. Roberts tucks engaging classroom activities into this already thematically robust tale—like the fizzy social dynamics in an experimental initiative-building class called Discoveries, the ins and outs of creating a garden of native plants, and tagging monarch butterflies—as she artfully tracks a profound transformation in her protagonist’s sense of self. The changes may be Bunny’s doing, but she’s helped along by a generously sized cast of almost uniformly supportive adults and peers (plus one great dog). By the book’s buoyant end, even one prickly girl’s repeated insistence that she’s not Bunny’s friend is sounding hollow. Bunny is cued white, and there’s some racial diversity in the supporting cast.
