What’s it about?

The story.

Where does water come from, and where does it go? In Once Upon a Raindrop, poet James Carter answers with a flowing, rhythmic poem that carries young readers on the journey of a single drop of water – rising as vapour, gathering into clouds, falling as rain, running to rivers and seas, and beginning all over again. The worlds of poetry and non-fiction meet here to make something rare: a picture book that is both a lovely read-aloud and a real introduction to the science of the water cycle. Carter's playful, musical verse is paired with Nomoco's fluid, luminous artwork, and the book closes with clear factual notes that deepen the wonder. Supporting the primary-school topic of water, it's an ideal bridge between story time and science lessons – a book that makes children look at a puddle, a cloud or a raindrop and want to know more.

Why it lands

Why they love it.

Why kids love it

Riding along with a single drop of water as it turns to cloud, falls as rain and rushes to the sea makes the water cycle feel like an adventure. The bouncy, rhyming words are fun to say aloud, and the swirling pictures are lovely to pore over.

Why parents love it

James Carter's musical verse turns the water cycle into a genuine pleasure to read aloud, while Nomoco's artwork is a thing of beauty. With clear factual notes to back it up, it bridges story time and the classroom water topic effortlessly.
