One December afternoon, a boy, his dog, and his grandfather take a walk to watch the sun begin to set over the river, in this book for readers 4 to 8 by the author of the Caldecott Honor Books Snow and How I Learned Geography. As nature's lights go out, the city's lights turn on, revealing brilliant Hanukkah, Kwanzaa, and Christmas displays. Uri Shulevitz's quiet, awestruck text is complemented by his watercolor and ink illustrations, in which meticulously blended colors convey the approach of nightfall.
