The morning after a snowfall a dog family heads out to the “best sledding hill in the / whole / wide / world.” Piling onto their sled, they swoosh “down the hill / faster than the speed of sound” before a BIG bump launches them into the air with the geese, sled and all. In his authorial debut, Harper nails the excitement of a swoop down a pristine hill. He depicts his dogs as floppy-eared brown hounds all bundled up in boots, parkas, hats and mittens. The full-bleed paintings place them in a wintry wilderness, surrounded by evergreens. This is a celebration of snow and speed, pure and simple—readers will understand exactly why, after landing with a bone-rattling SPLOOMPH, the kids have only one thing to say: “Again! Again!” (Picture book. 2-5)
