Everyone at Sweet Valley Middle School is going to the biggest concert ever... everyone except twins, Jessica and Elizabeth! Their favourite band is back in town but no matter how much they beg their parents, they can't get permission to go. Elizabeth is ready to sulk and stay home, but Jessica refuses to give up hope. She'll see this band even if it means lying or leaving her sister behind. Caught between her parents and her twin, will Elizabeth sneak out with Jessica? Or will she blow the whole plan out of the water?
