What’s it about?

The story.

A young boy asks his grandmother a simple, enormous question: what is love? "I can't answer that," she tells him, so the boy sets off into the wide world to find out for himself. Along the way he meets a fisherman, an actor, a carpenter, a poet and many more, and every single one of them has an answer to his question. Love is a fish. Love is applause. Love is a house you build. But not one of the answers feels quite right, and the boy keeps walking and wondering, until at last he begins to understand that the truest answer may have been waiting for him all along, somewhere much closer to home. Written with Mac Barnett's deceptively simple, folktale-perfect voice and illustrated in Carson Ellis's spectacular, richly detailed style, What Is Love? has the timeless feel of a modern classic. A gorgeous, philosophical picture book that gives children, and the grown-ups reading with them, a great deal to think and talk about.
