Jules is a third grader at last! But so far, the reviews aren't so good. Her new teacher makes her feel totally tongue-tied. Charlotte shows up on the first day wearing the one thing Jules really wants but will never get. And she already has homework - researching a famous person to become for the class wax museum project. But how will she decide who to be when she barely knows who she is in the first place?

Even worse, her after-school sitcom rehearsals are harder than ever - and the TV show is about to air for all the world to see. Jules needs to find her inner superstar if third grade is ever going to be a smash hit.
