Battle of the Bands (Stories from East High #1) by Walt Disney Company, N.B. Grace

East High is putting on its first-ever Battle of the Bands! Troy and his basketball buddies are looking forward to living out their rock-star fantasies, and Sharpay has formed her very own girl group. But while Troy and Sharpay prepare to step into the spotlight, Gabriella and Ryan are left in the shadows. Gabriella keeps herself busy by tutoring Ryan, who needs help with algebra. Still, she can't help wondering why Troy wouldn't want to join forces with her for the Battle of the Bands. Didn't the two of them make a great team at the musical? Maybe it's time for Gabriella to take the stage on her own.
