One December afternoon, boy with dog and grandfather with beard take a walk to watch the sun begin to set over the river. When the sun drops low in the sky, they start home. Buildings grow dimmer. People are rushing. As nature's lights go out, one by one, city's lights turn on, revealing brilliant Hanukkah, Kwanza, and Christmas displays in streets, homes, and stores. A stunning picture book that's sure to be a winter holiday classic by Caldecott Medalist Uri Shulevitz.
