What’s it about?

The story.

After a summer of sunburn, Lottie Brooks is off on a week-long residential trip to Camp Firefly with her class, escaping her embarrassing parents and revolting little brother. It should be an adventure of abseiling, raft-building and blindfold sensory trails, but disaster strikes on every front. Her best friend Jess is suddenly glued to new girl Isha, the camp is also hosting a pack of snobby, mean girls from a private school, and then the unthinkable happens: Lottie's diary is stolen and read out loud for everyone to hear. Faced with humiliation, homesickness and friendship wobbles far from home, Lottie has to find some genuine courage and work out who her real friends are. Told in Katie Kirby's diary of doodles, lists, thoughts of the day and glorious over-sharing, the fourth Lottie Brooks book bottles every excruciating and hilarious thing that can happen on a school trip, and reminds readers that surviving the disaster is its own kind of victory.

Fit check

Right for your child?

Where it lands by age

A 9-12 independent read that pairs naturally with a class residential trip. The mean-girls and stolen-diary storylines carry mild social sting but resolve warmly, and the diary format keeps it quick and reluctant-reader friendly.

About the author & illustrator

Katie Kirby

Writer & illustrator · United Kingdom

Katie Kirby is a British author-illustrator who lives by the sea in Hove, best known for the bestselling Lottie Brooks series. After a career in London advertising and a hit parenting blog and book, Hurrah for Gin, she turned to children's fiction with The Extremely Embarrassing Life of Lottie Brooks, a diary of doodles, lists, text threads and glorious over-sharing that follows Lottie through the agonies of secondary school. Wrong pencil cases, first crushes, friendship wobbles and mean-girl cliques all get the cringe-comedy treatment, but there's a genuinely anxious, hopeful heart underneath. Painfully relatable and laugh-out-loud funny, the series is a UK favourite for 9–12s and a natural next step for readers who love Dork Diaries and Diary of a Wimpy Kid.
