Lucy's mum is so out of date she's practically mouldy.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.

Katie Dale had her first poem, 'The Fate of The School Hamster', published in the Cadbury's Book of Children's Poetry aged just eight and hasn't stopped writing since! Inspired by her mother, Elizabeth Dale, who is also an author, Katie loves creating characters, both on the page and onstage. After training as an actress and touring the country as Shakespeare's Juliet, she was a winner of the SCBWI Undiscovered Voices competition, which launched her writing career. She has published books for toddlers up to teens, and her novels have won several awards and are published all over the world. Mumnesia is her first novel for Macmillan Children's Books.
