What’s it about?
The story.
Finn wants to fit in. At his new school, everyone seems so impressive, and the truth about Finn doesn't feel like enough. So he tells a small fib. Then another. Each fib snowballs into the next, growing larger and more elaborate, until Finn has no idea how to find his way back to honesty. Tom Percival uses his characteristic visual device, fibs given a physical, visible form, growing and multiplying across the pages, to make the internal experience of compulsive fibbing legible to young readers. The book doesn't treat lying as simply bad behaviour to be corrected but as something children do when they're afraid: afraid of not being enough, afraid of not belonging. The resolution asks Finn to come clean and finds that the truth is both frightening and, ultimately, a relief. A practically useful book for conversations about honesty that approach the topic from the child's perspective rather than the adult's, why lying feels necessary, and what it costs. Good for starting school, new social situations, and children who tend toward social anxiety.

In the classroom
How it works in school.
Tom Percival's flagship emotional-literacy series — each picture book explores a big feeling (worry, anger, shyness, jealousy and more), making them the go-to PSHE read-alouds.
A book children love that happens to support school — never a stand-in for the texts a class is taught with. Reviewed for the classroom · June 2026.
Why it lands
Why they love it.
Why kids love it
The specific recognition is fibs snowballing — Finn telling a small lie at his new school, then needing another to cover it, the fibs given physical form and following him around getting bigger. The Big Bright Feelings about why honesty is hard and what the lying actually costs.
- Being understood finally
- Friendship and belonging
Why parents love it
The Big Bright Feelings on lying — Finn's fibs given a physical, visible form that small children grasp instantly. Useful for the conversation about why children fib in the first place (fear of not being enough), without making it a telling-off. Particularly good around starting school.
