The shape of it

The shape of this universe.

The Shape Trilogy is Mac Barnett and Jon Klassen's spare, clever picture-book sequence about Triangle, Square and Circle. The books look simple, but they are unusually slippery: tiny changes in expression, pauses, empty space and ambiguous endings do a lot of the storytelling. Across the trilogy, the shapes trick, misunderstand, create, worry, judge and forgive one another, giving young readers funny, elegant stories about friendship, identity, trust and moral uncertainty. It is a superb fit for families who enjoy picture books with restraint, wit and room for interpretation.
