Lucy's mum is so out of date she's practically mouldy.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 Valentine's 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? Mumnesia by Katie Dale is a hilarious story about a very unusual mother-daughter relationship.
