Tegan and Sara may have survived seventh grade, but their junior high jams are just beginning. Offstage, school is officially back in session. Between Sara's growing feelings for her dream girl and Tegan's falling out with her former BFF, eighth grade might prove to be even messier than last year. Onstage, the twins are swept up in a battle-of-the-bands contest to open for their favorite musical artist, landing them with a new manager, new opportunities, and new challenges, too. But stepping into the spotlight -- and into their true selves -- means colliding over fame, family, and finding their sound. In this spunky, big-hearted conclusion to the autobiographically inspired story launched in Junior High, the sisters realize that to get the gig that could change their lives forever, they'll have to first figure out who they are and how to get along.
