Interesting premise, well executed. Being the manager of a rock band is an exercise in cat-herding and ego-massaging at the best of times. Throw in the high school drama/angst of who likes who and who suddenly hates who. Then have a deaf girl try to be the person to cattle-prod them to rehearse, change their image to suit their audience, and generally prevent imploding and self-destructing.
At the same time Piper is dealing with anger at her parents. Piper's grandparents were both deaf and left her a college fund so she could go to Gallaudet. However, her baby sister Grace was born deaf so her parents raided Piper's college fund to pay for a cochlear implant for her. Now not only will Grace hear better than Piper ever will, her dad is unemployed so they may not be able to pay for college. Meanwhile her parents dote all over Grace and are clueless how hurtful some of their actions are to Piper.
So Piper has a month to prove herself as a manager, keep her crapmobile (aka USS Immovable) running, mourn her fellow deaf BFF moving, survive her home life, keep her younger brother from perpetual detention, and deal with a drummer who might mean a lot more to her than she realizes.
