From the award-winning team behind Sam and Dave Dig a Hole, and illustrated by Jon Klassen, the Kate Greenaway-winning creator of This Is Not My Hat and I Want My Hat Back, comes the first tale in an exciting new trilogy. Meet Triangle. He is going to play a sneaky trick on his friend, Square. Or so Triangle thinks… Visually stunning and full of wry humour, here is a perfectly-paced treat that flips the traditional concept book, and approaches it from a whole new angle.

Every day, Square brings a block out of his cave and pushes it up a steep hill. This is his work. When Circle floats by, she declares Square a genius, a sculptor! “This is a wonderful statue,” she says. “It looks just like you!” But now Circle wants a sculpture of her own, a circle! Will the genius manage to create one? Even accidentally?

Triangle and Square are visiting Circle, who lives at the waterfall. When they play hide-and-seek, Circle tells the friends the one rule: not to go behind the falling water. But after she closes her eyes to count to ten, of course that’s exactly where Triangle goes. Will Circle find Triangle? And what OTHER shapes might be lurking back there?
