Katie is going to have to face the music...

Katie Cox (overnight singing sensation and owner of the World's Worst Bangs) never meant to become a pop star. And she didn't mean to start a war with Karamel (aka the World's Cheesiest Boy Band).

Now her first concert is just days away. Cool? Maybe. Terrifying? Definitely. And with her school friends more interested in her fame than her feelings, and an army of Karamel fans ready to take her down, this battle goes way beyond the charts.
