The Real Rebecca

My name is Rebecca Rafferty, and my mother has ruined my life. Again.
I didn't mind her writing boring books for grown-ups. But now she's written one about an awful girl my age and everyone thinks it's me!
Including the boy who delivers our newspapers, aka Paperboy, aka the most gorgeous boy in the whole world. Oh, the shame!
And if that wasn't awful enough, the biggest pain in my class wants to use my 'fame' to get herself on the reality show 'My Big Birthday Bash'.
I've just got to show everyone the REAL Rebecca. But how?
