Square's efforts to please are equal parts hilarious and cringeworthy, and the moment he topples over in exhaustion is comic gold. The story's decidedly ambiguous conclusion leaves the door open for questions about what it means to be an artist--and that's the whole point. --Publishers Weekly (starred review) Funny and lightly philosophical, Barnett's story gets an extra punch of hilarity with Klassen's minimalist graphite-and-watercolor artwork. A must for Triangle fans that will leave them wondering how this geometric drama will end. --Booklist With typically deceptive minimalism Klassen places a few flat, blocky shapes on the white pages to suggest the physical landscape, angling Square's body and glance to convey the emotional one. Humor is in the details: a bit of twig that catches on harried Square's head and stays there; the shadow that appears beneath Circle as she floats along through the air. For all its brevity, chockablock with philosophical topics to ponder and debate. --Kirkus Reviews
