What’s it about?
The story.
In a land of big animals, one small mouse is always overlooked. Fed up, he decides he needs a roar, and sets off to find the lion to ask for one. The lion, it turns out, is not entirely fearless either. Mice, in fact, are exactly what lions are afraid of. Rachel Bright's rhyming text builds to a warm, funny reveal: that the qualities we think belong to others are often already inside us, and that the most unlikely pairs can help each other find them. Jim Field's expressive animals, the mouse's wobbling determination, the lion's barely-concealed panic, do most of the emotional work. The best starting point in the series and the one most widely used in UK schools to talk about courage and self-belief.

In the classroom
How it works in school.
Rachel Bright's warm, rhyming animal fables about courage and kindness — superb read-alouds for joining in and talking about feelings.
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 delight is the reversal — a tiny mouse wants to roar like the lion, climbs the mountain, and discovers the lion is scared of mice. A four-year-old gets the satisfying flip of expectation, plus the underlying message that being small doesn't mean being powerless. Reliable confidence-builder.
- Friendship and belonging
- Making a difference
- The underdog winning
- Trickery and cleverness
Why parents love it
The picture book to hand a small child who feels small — Bright's tight rhyming couplets, Field's expressive animals, and the size-flip ending that lands every read-aloud. The first in the series and the one most worth owning. Often a child's first 'courage' book.
- Shared humour
- Bedtime appropriate
- Quick to read
- Conversation starter
