From hilarious MEGA bestselling author, Katie Kirby, comes a brand-new diary in the phenomenal Lottie Brooks series!

Shortlisted for Book of the Year – Children’s Fiction at British Book Awards 2026

Today we brainstormed strategies to #GETAMBERBACK. Our top ideas are:

Send her flowers
Hypnotise her
Kidnap her
Tell everyone she smells like lasagne
Emotionally blackmail her by making a BFF photo montage

Just when Lottie thought life might be going back to normal, everything goes wrong again! Amber’s hanging out with the Ultra Mean Girl Gang at school and is completely ignoring the Queens of Eight Green. Mum’s gone back to work and expects Lottie to ‘help around the house more’, Bella keeps biting everyone and Pot Noodle will not stop sniffing every dog’s bum. DISASTER!

Now Lottie has to come up with a foolproof plan to get Amber back before her friendship group is destroyed forever. What could go wrong???

Join Lottie as she battles the mean girls, takes on school injections (apparently they can go through your arm!) and even more extremely embarrassing moments.

Readers LOVE Lottie Brooks:
My daughter couldn't put it down and read it in 2 days. Read at breakfast, walking downstairs, tea time, in the bath.
My 9-year-old daughter devoured it in two nights, and all I could hear from her was giggling and the occasional "Mum! Listen to this! This is SO me!".
My 12 year old reluctant reader took this book, read 100 pages in one night and proclaimed it 'the best book ever'
Katie has managed to capture the essence of what this group think and feel in a positive, life-affirming fashion'
