Part of the Shapes Trilogy, the books that inspired Shape Island from Apple TV+.

Multi-award-winning, New York Times best-selling duo Mac Barnett and Jon Klassen conspire again on a slyly funny tale about some very sneaky shapes.

Meet Triangle. He is going to play a sneaky trick on his friend, Square. Or so Triangle thinks. With this first tale in a new trilogy, partners in crime Mac Barnett and Jon Klassen will have readers wondering just who they can trust in a richly imagined world of shapes. Visually stunning and full of wry humor, here is a perfectly paced treat that could come only from the minds of two of todays most irreverent and talented picture book creators.
