After an eight-year interval, a Beginner Book by this well-loved originator of the series is welcome; and since Seuss hasn't chosen to illustrate it himself, we are lucky to have Stevenson as alternate. In the familiar Seuss pattern of a simple premise exaggerated to comic effect, a boy declares, "My bed is warm. My pillow's deep. Today's the day I'm going to sleep"--regardless of his mother, various arguments, successive waves of reinforcements, including the Marines, and a TV crew filming the momentous event. Actually, the development of the idea is a little tame compared with Seuss' other extravaganzas (and such determined all-day slumber is more the province of teen-agers and the good doctor's contemporaries than of readers at this level); but the book is delightfully enlivened by Stevenson's vigorous illustrations, which considerably augment the text by showing the full extent of the consternation caused by the hero's stubborness. Though there is plenty of the repetition required by learning readers, there are also some unusual words like Memphis, suggesting that this is not the easiest easy reader; but it has enough appeal to keep beginners entertained.
