Girl, aloud - Emily Gale

Kass Kennedy is in the spotlight, thanks to her Dad. He plans on
selling her soul to the Devil - or at any rate to Simon Cowell when
she finds herself pushed into an X-Factor audition. Kass could
just say no, but her dad's manic-depressive mood swings are a constant
worry and he has her in an emotional half-Nelson.
Just when things couldn't get worse, Kass falls for a gorgeous older
boy, also named Cass. She's amazed when he appears to like her,
but it turns out this boy, is her best friend's long-term crush.
What's a girl to do? Everything Kass thought she understood starts
to fall apart and the only person she can turn to ... grumpy Simon
Cowell (literally in her dreams!). She might not be able to sing
her way out of a paper bag, but Kass discovers that she isn't
a choker when it comes to sorting out real life.
