Thirteen-year-old Alondra was born into a musical family.

Her dad, the former frontman of a famous alt-rock band, expects her and her sisters to follow in his footsteps. The girls have formed their own band, which will open for their dad during his comeback tour.

Despite secretly liking quieter music, Alondra is committed to preparing for the tour. She'll do whatever it takes: Change the sound of her voice. Suppress her discomfort with some fans' behavior. Act the part of a hardcore riot grrrl.

But when a classmate invites her to join a choir club, Alondra discovers a new way of making music. Choir lets her express herself in ways that the band doesn't.

Afraid to upset the delicate balance in her family, Alondra secretly practices with the choir between shows with her sisters' band―until her secrets are exposed. Will she be forced to choose between her two voices, or can she bring the different parts of her life into harmony?
