Babymouse is a likably imperfect character whose endearing humility and every-school-age-girl insecurities are transformed into comedy by her rich imagination. She is rendered in playful, wavering lines which reflect her winsome uncertainty, while the pink, white, and black palette gives the book obvious "girl" appeal. The many endearing comedic moments in the story -- in which Babymouse tries to overcome her fear of a mandatory dodgeball game against her nemesis (and school bully) feline Felicia Furrypaws -- exist in direct contrast to the crueler, darker ones in which Felicia torments Babymouse. The torments include elbowing Babymouse in the hallway, "accidentally" spilling Babymouse's drink at lunch, verbally threatening her, and shutting her in her locker. Even Babymouse's triumphant defeat of Felicia, where she nails her in the head with a dodgeball, is bittersweet in its cruelty. Much to my surprise, none of the participants in my girls' book group -- ages 6-8 -- were upset by Felicia's bullying (perhaps because Felicia's torments are so exaggeratedly over-the-top that they are unbelievable?), and all were pleased with Babymouse's method of triumph. Even so, I think the darker turns in this book make it appropriate for older elementary ages, perhaps 9 and up.
