A young Black girl is asleep in her bed with her red-collared black cat when a blue-collared black cat appears through a porthole of light. The blue-collared cat absconds with the red-collared cat’s red mouse toy. The red-collared cat follows through the hole, as does the now awake little girl in her red planetary nightgown. She emerges (bottom of page spread) in a bright white space with her beaded hair rising from her head while her upside down cat (top of page spread) disappears through another hole. Her ongoing adventure offers one captivating surprise after another, from an Escher-like staircase to a lively cast of diverse children joyfully engaged in play, with one another and with their doppelgangers, whom they encounter as they move through various holes. The girl, too, discovers her multiverse “twin,” distinguished from her, as are the individual children in the other pairs, by elements of clothing color. What does it all mean? That’s up to readers to decide in this creative wordless outing with much to delight in, discover, and ponder. The mixed-media illustrations use simplified shapes and bright colors against (mostly) white or black backgrounds, with the masterful composition an essential part of how meaning can be made.
