A prose portrait of the city at night shows all the things that go on while a little girl sleeps. The city’s “soaring towers glow. Its people work—no matter what the hour.” It is obvious that Wellington is in love with big-city living, using its many facets in one fascinating night. Dancers rehearse, firefighters put out blazes, the staff cleans an office building, an artist goes to work in her studio, a night watchman makes his rounds at a museum in just a few of the congenially depicted scenes. Dark backgrounds make Wellington’s characteristic dots and squares of color glow, while her familiar mice and cats frolic through every scene. The text imparts plenty of information, offering windows on new worlds for children; all the while the little girl sleeps, secure in her vital, vibrant home town. (Picture book. 4-8)
