How to Rock Best Friends and Frenemies

After a humiliating tumble down the social ladder, Kacey Simon is back on top, where she belongs. She's lost her lisp, traded in her Coke-bottle glasses for contacts, and learned that brutal honesty isn't always the best policy. Best of all, she's made up with Zander and her BFFs and reclaimed her spot as Gravity's lead singer. Her life is pitch-perfect - until Zander's ex-girlfriend, Stevie, arrives in town. Marquette Middle hasn't seen a girl with such killer style and impressive vocals since...well, Kacey herself. Boys want to date Stevie, girls want to be her, and Kacey wants to boot her butt out of Chicago ASAP. But when Kacey reverts to her mean-girl ways to take Stevie down, will she lose the band - and Zander - for good?
