In the fourth installment in this graphic novel series, the singular mouse sets her sights on musical stardom. And if that proves a little too ambitious, then moving up from last chair in the school band flute section would be enough. As usual, Babymouse’s imaginary life progresses at a pace that far outstrips her reality, but with some hard work and the help of classmate Penny Poodle, Babymouse achieves her own small degree of success. Daydreams that include a trip to Oz, a recording contract, a stint as Pied Pipermouse, and her own music video provide plenty of fodder for readers’ own fantasies of diva-dom. Rock on, Babymouse! (Ages 8–10)
