It all started with a Special Project: Solve a mystery in your own life. For seventh grader Bethesda Fielding, one mystery is too tempting to ignore. She’s convinced that her mousy Music Fundamentals teacher is hiding a secret life. But no one is prepared for what she discovers. Ms. Finkleman used to be . . . a rock star? Soon the whole school goes rock crazy, and a giant concert is in the works, led by none other than timid Ms. Finkleman! But is the case really closed or could there be even *more* to the story of Ms. Finkleman? With the help of her rock-obsessed classmate, Tenny Boyer, Bethesda won’t stop until she solves this mystery once and for all!
