If I'd known that two million people were going to be watching, I'd probably have done a bit of tidying up.

Katie Cox is used to going unnoticed - by her mum, her dad, even her best friend. But when a video of her singing in her bedroom goes viral, she becomes a superstar overnight. As the views skyrocket and a recording contract beckons, the real world starts to feel very far away.

And now Katie's riding high on her newfound fame. But the higher she goes, the further there is to fall . . .

Accidental Superstar by Marianne Levy is the first in a hilarious series about a girl who accidentally finds fame singing online.

Marianne Levy spent her twenties as an actor. She was in various TV shows, did some comedy on Radio 4 and made a brief appearance in the film Ali G Indahouse, where she managed to forget both her lines. She then worked as a continuity announcer for Living TV, introducing, and getting obsessed with, America's Next Top Model. She's been the voice of a leading brand of make-up, a shopping centre and a yogurt. Marianne is the author of the Ellie May young fiction series for Egmont and a regular contributor to the Independent on Sunday. She lives in London with her husband, daughter and a bad-tempered cat.
