Trickling, bubbling, swirling, rushing, a river flows down from its mountain beginnings, past peaceful country and bustling city on its way to the sea. Hooper (T, 1998, etc.) artfully evokes the water’s changing character as it transforms from “milky-cold / rattling-bold” to a wide, slow “sliding past mudflats / looping through marshes” to the end of its journey. Willey, best known for illustrating Geraldine McCaughrean’s spectacular folk-tale collections, contributes finely detailed scenes crafted in shimmering, intricate blues and greens, capturing mountain’s chill, the bucolic serenity of passing pastures, and a sense of mystery in the water’s shadowy depths.
