Thirteen-year-old Tig Ripley has plenty of good reasons for starting an all-girl rock band. Never mind she doesn't play an instrument—she'll figure that out. Fronting a band is sure to propel her out of the background and into the spotlight at her middle school. So after a few weeks' worth of drumming lessons under her belt, she starts assembling her band. With her cousin Kyra agreeing to play bass, soon Tig has her piano-playing friend Olivia down for the keyboard. And then she convinces tough girl Robbie Chan to sign on as lead guitarist. With a cool name—Pandora's Box—all the band needs now is a killer lead singer. How hard can that be? But when Kyra invites obnoxious diva Haley Thornton to join the band, Tig realizes snagging a lead singer—the right lead singer—is not going to be easy. Everyone says the drummer is the heartbeat of a band—does Tig have what it takes to lead Pandora's Box?
