What’s it about?
The story.
Iris and Isaac are not friends, at least, not at the start of this story. After a falling-out, the two polar bears stomp away from each other across the snowy landscape, determined to be apart. But as they wander, each sees strange, funny and wonderful things, and each slowly realises that the joy of discovery is smaller when there is no friend to share it with. Catherine Rayner turns a familiar early-childhood situation, a quarrel between friends, into a spacious, tender Arctic journey. The text is simple and readable, but the emotional pattern is precise: anger, distance, wonder, missing someone, and coming back together. The illustrations are luminous and expressive, giving the polar bears real weight and warmth. It is an excellent read-aloud for friendship repair, sharing, saying sorry without forcing the word, and helping children understand that feelings can soften.
