What’s it about?

The story.

Lottie Brooks is about to start secondary school, and everything is going wrong. Her best friend Molly has moved to the other side of the world, she's got the wrong pencil case, she still hasn't got a bra, and now the whole class is calling her KitKat Chunky. Convinced the only way to survive is to worm her way in with the popular girls, Lottie hatches a plan that quickly proves to be a very bad idea. But when she meets Jess, a girl who genuinely doesn't care what anyone thinks of her, Lottie starts to work out who she actually wants to be. Told entirely through Lottie's diary of doodles, lists, thoughts of the day and hilarious over-sharing, this is a warm, painfully relatable comedy about first days, first crushes and the agony of being eleven. The opening book in a bestselling series for readers who love Dork Diaries and Diary of a Wimpy Kid.

Fit check

Right for your child?

Where it lands by age

Squarely a 9-12 independent read, pitched at the anxious edge of primary-to-secondary transition. The short diary entries and doodles make it very friendly for reluctant readers, and it works as a shared read for a child navigating the move to big school.

Why it lands

Why they love it.

Why kids love it

Lottie says out loud all the mortifying things kids actually worry about, from bras to the wrong pencil case to being nicknamed KitKat Chunky. The doodles, lists and thoughts of the day make you feel like you're reading a real friend's diary.

  • Being understood finally
  • Friendship and belonging
  • Proving yourself
  • Breaking the rules safely

Why parents love it

It captures the anxiety of starting secondary school so accurately it hurts, then makes it funny. Reluctant readers race through the diary format, and the message about being yourself rather than chasing the popular crowd lands without preaching.

  • Shared humour
  • Quick to read
