You can read it as a story about love, generosity, parenthood, growing older, or even about how easy it is to take something for granted when you assume it will always be there.

The illustrations by Aristides Ruiz and Joe Mathieu are bright and full of movement, perfectly matching the rhythm and excitement of the text. We stopped on nearly every page to look closer at the butterflies and talk about what was happening. It’s always fun when a book becomes both a story and a mini science lesson without feeling like one.
