Have you ever just wished your mum would just grow up?
Lucy's mum is so out of date she's practically mouldy. She's super-strict, overprotective and won't let Lucy go to the school ball! Lucy can't believe she was EVER a teenager...
Until the morning her mum wakes up with no memory of the last thirty years - and thinks she's twelve years old!
All Lucy wants is for her mum to go back to being her old self - but how?
