Things That Go

This addition to a lift-the-flap series centers on vehicles and the arenas in which they function. Settings include a subway station, an airport, outer space, and a construction site. Several flaps are incorporated into each cardboard spread; opening the flaps allows for glimpses inside vehicles as well as other bits of information or questions: "Some diggers have wheels. Others have tracks, like the bulldozer below." The array of historical facts and other topical details add up to an educational and entertaining package. Ages 3%E2%80%93up. (June)
