An allegorical fantasy in which a group of young people are guided through the universe by Mrs. Who, Mrs. Which and Mrs. What -- women who possess supernatural powers. They traverse fictitious regions, meet and face evil and demonstrate courage at the right moment. Religious allusions are secondary to the philosophical struggle designed to yield the meaning of life and one's place on earth. Young Meg's willingness to face IT in the form of a black beast in order to save a dear friend is one sign of her growing awareness. Readers who relish symbolic reference may find this trip through time and space an exhilarating experience; the rest will be forced to ponder the double entendres.
