On a class visit to the Empire State Building, a young boy who gets separated from his class, unknowingly crosses the line between fantasy and reality while he’s on the top floor, up among the clouds. He’s befriended by a small cloud, in fact, who whisks him away, up into the sky into a building known as Sector 7. Here stern bureaucrats submit their boring sketches of proper cloud shapes and launch the same old amorphous, cumulus masses into the skies over Manhattan. Our hero and his cloud friend, however, have other ideas and his sketches of fish catch on quickly among the clouds, much to the frustration of the bureaucrats. Weisner’s detailed watercolor paintings tell the whole story in this original, funny wordless book. (Ages 4-9)
