"Robinson's first book as both author and illustrator is a gentle, wordless wonder." - The New York Times Book Review * "Simple geometric shapes and expanses of empty space make the spreads easy to consider, and Robinson nails the pacing, using each page turn for a comic or conceptual beat. Almost all children wonder whether there are others exactly like them somewhere out in the universe, doing the same thing at exactly the same time. By playing with that idea while juxtaposing similarity and difference, Robinson creates an almost mystical Droste effect of a story that is all mirrors and windows for the group of various children who are offered portals to reach one another. He also creates a speculative world with its own logic, and an adventure that will both puzzle and amuse." - Publishers Weekly, starred review * "The simple geometry of Robinson's work comes alive in this expanse of wordless narrative. A fearless use of white space and an utter disregard of conventions of direction encourage readers to engage with the physical book as the story unfolds, touching and turning it as they literally take the narrative into their hands. A bright, open primer for Escher." - Kirkus Reviews, starred review * "Both beautiful and fanciful...vibrant shapes reminiscent of Paul Klee or Piet Mondrian fill the pages.... A work of art and celebration of childhood for all libraries." - School Library Journal, starred review "The brightly colored illustrations pop against a pure white background. Children, some upright and some upside down, are shown in a variety of clothing and skin colors, partaking in various activities. Is this a parallel universe, or is it all a dream? Readers will decide, and a little blue mouse may help with the final decision." - Booklist "Our protagonist, a brown-skinned explorer with a headful of bouncy beaded braids (which fetchingly fall up as she first pokes her head through the portal where up is down) is clearly a fan of other worlds (her nightie sports a red image of Saturn in complement to the mirror girl's blue, and she's looking into a telescope on the back cover) who's made for exploring, and her cat's silent but determined progress provides an entertaining visual thread. The youngest viewers may enjoy decoding the girl's journey with some adult assistance, while more book-savvy kids will get a kick out of 'reading' the story all on their own." - BCCB * "Smart, sly, and imaginative." - Horn Book Magazine, starred review "In this exhilarating wordless picture book, a girl and her cat enter a portal to a physically skewed world where they encounter, among other things, their doppelgangers." - Shelf Awareness * A "multilayered, mind-blowing and truly out-of-this-world adventure." - BookPage, starred review
