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.
