In "The Alphabet from Z to A (With Much Confusion on the Way), " Judith Viorst once again applies her clear-sighted wit to a subject of universal appeal, turning the traditional alphabet book on its head by going through the alphabet backwards. Viorst's lively verse irreverently demonstrates that the spellings and sounds of our language are often so maddeningly inconsistent -- "blue" and "blew," "chute" and "shoe" -- that, as her exasperated narrator complains, "It could drive you berserk." Aimed at children who already have some facility with language (and at anyone else who likes to play with words), "The Alphabet from Z to A" is an entertaining and thought-provoking romp through the quirks and quagmires of the English language. Richard Hull's exquisite drawings enrich the text and offer a playful challenge.
