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.

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.

Classroom role

  • Read aloud

Good for teaching

  • Theme

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.

  • Conversation starter
  • Bedtime appropriate
  • Quick to read
  • Great writing

About the author & illustrator

Tom Percival.

TP

Tom Percival

Writer & illustrator · United Kingdom

Tom Percival is a British author-illustrator born in Shropshire, best known for the Big Bright Feelings picture-book series, Ruby's Worry, Perfectly Norman, Ravi's Roar, Meesha Makes Friends, The Invisible, which gently externalises children's emotional experiences through visual metaphor. Worry is a small yellow shape that grows larger when ignored; Norman's wings are a bright feathered thing he tries to hide. The books have become a fixture of PSHE / SEL reading in UK schools and parent-led conversations about feelings. Percival also writes the Dream Team chapter-book series and other picture books. His visual style is bright, contemporary and inclusive, and his books are well-suited to children processing anxiety, difference, or big emotions.
