«Klassen.s palette is quiet, his weathered backdrops are elegant, and his comic timing is precisely synched to Barnett.s deadpan prose. Triangle fools Square, and the story fools readers... Instead, Triangle seems to win this round, even if he does finish the book trapped in his own home. Whereas the humor in Sam and Dave Dig a Hole was subtle and sly, this shape showdown is pure, antic buffoonery.»

Publishers Weekly

Barnett and Klassen, whose previous collaborations.Extra Yarn (2012) and Sam and Dave Dig a Hole (2014).were Caldecott Honor Books, have created a marvelously clever picture book.The simple sentences and repetition are perfect for a young audience, who will be raptly interested in the devious dynamic between the friends. Judging by this offbeat first volume, Barnett and Klassen.s planned trilogy is shaping up to be an excellent one.

Booklist

«Klassens minimalist visuals make for beautiful, surreal landscapes as the shapes go back and forthBarnetts even-more-minimalist narrative leaves gaps of many shapes and sizes for readers to ponder.»
