Little children will love this going to sleep book -- a really fresh idea by a talented and prolific author, illustrated by Clement Hurd. In a soft sing-song, here is a bunny saying goodnight room, goodnight moon, goodnight to all the familiar objects in the softly lighted room. Then- as the room darkens, in successive pictures, the goodnight ceremony moves forward. The colors range from a bright, crisp red, green, yellow, to an almost black background. Despite the high price, which takes it out of the straight merchandise market, this is a good buy, from quality of text and pictures -- and most of all, idea.
