Triangle

K-Gr 2—A pair of practical jokes will have readers debating who started it in this picture book from the deadpan duo. Readers first meet Triangle, a simple shape with two large eyes and a sturdy pair of legs. Triangle declares that he's going to play a "sneaky trick" on Square, so he sets off across a backdrop of triangular landmarks, through the slightly wilder land of waterfalls and "shapes with no names," into a region of squares to the house of Square, a similarly wide-eyed figure. Hiding outside and hissing like a snake, Triangle frightens Square and soon finds himself fleeing across the sparse landscape, with Square in hot pursuit. Returning to the safety of his triangular home, Triangle discovers that Square has a surprise of his own in store. But was Triangle the original instigator, or was turning the tables always Square's plan? Klassen's distinctive style of digital graphite and watercolor illustrations with lots of white space is well suited to the focus on simple shapes and a circular narrative that ends where it began. The horizontal movement from Triangle's abode to Square's house and back follows a clear line, with plenty of visual cues linking the text and illustrations. Both the occasionally repetitive text and the images make this title a good match for emerging readers. The characters convey an appropriate level of shifty expression through the movement of their eyes, and the ambiguous ending will elicit plenty of opinions from young audiences.
