This elaborate pop-up book adds a spectacular twist to Mother Goose"s well-loved rhymes. Paper artist Robert Sabuda, preeminent patriarch of modern pop-up engineering, brings yet another explosion of motion and color to his latest masterpiece. Attributing animal personalities to nursery-rhyme characters, he surprises young readers time and again. In "Jack Be Nimble," for example, the fellow leaping lithely over a candlestick is none other than a grasshopper. And the Man in the Moon is seen from a startling perspective: he has decidedly alien features! Sabuda"s quirky take on traditional rhymes, combined with his fantastic folding, moving, spinning paper sculptures, will have pop-up fanciers and Mother Goose devotees clamoring for more. Sturdier than most pop-ups, these three-dimensional constructions are nonetheless vulnerable to tiny grabbing hands. At his best, Sabuda creates breathtaking displays of pop-up craftsmanship, as in the "four and twenty blackbirds" bursting rowdily out of a pie, mirrored sunglasses on every one. At his worst, he creates slightly bewildering beings, such as the star-shaped Jill in "Jack and Jill" tumbling down a mysterious edifice. He may occasionally (and understandably--what a fun job!) get carried away with his engineering feats. (Ages 4 to 8) --Emilie Coulter
