Life, Starring Me! (Hardcover, Bound for Schools & Libraries ed.)

Ruby Day is a star. Or at least she was, until she got too old for her role on the international tour of Bye Bye Birdie. She knows all there is to know about Parisian room service, signing autographs for fans, and navigating strange new cities. But so what? Now Ruby is just an ordinary seventh grader, doomed to an ordinary seventh grade life.

That is, until she joins the totally unglamorous school musical and finds herself in a role she's never played before -- best friend.
