Vita is a purple-haired singing queen, and she has big dreams for her rock group, Zebrafish. But when she holds auditions for the back-up band, tryouts are sorely lacking in the musical ability department. Luckily her new bandmates—Walt, Tanya, Jay, and Plinko—have other talents. But lately Tanya has been missing a lot of rehearsals. When Vita discovers why, she realizes that the group can be about much more than one person, one band, or even one school. A concert won't cure Tanya's cancer or make her treatments any less painful, but, in their own way, Zebrafish can make a difference—and the tale of their unlikely success is sure to strike a chord with young readers looking to make their world a better place.
