The classic child's game of peek-a-boo becomes an exuberant guessing game in this compact, colorful board book from Laden ( When Pigasso Met Mootisse , 1998). Each of the riddles begin with the phrase "Peek a" on one page. The facing page contains a cut out in an enlarged keyhole shape, allowing the reader a brief glimpse of the underlying picture. Readers can then attempt to solve the puzzle before turning the page to reveal the complete picture. The rest of the rhyme is printed on the facing page, e.g., one riddle reveals a quixotic collection of cheerful animals. The answer? "Peek a Zoo," of course! Laden provides plenty of clues for the youngest reader. The artwork on each overlaying page is decorated in a theme to match the answer and the solution to every riddle always rhymes with boo. Color saturates every page, easily capturing a child's attention. The array of cheerful creatures (and one choo-choo train) populating the pages and Laden's whimsical rhymes make this a book little one's will reach for again and again. Companion book is Ready, Set, Go! (Board book. 13)

PreS-The exuberant illustrations in this guessing-game board book will enchant infants and toddlers. A bright left-hand page with the words "Peek a" faces a right-hand page with die-cut windows through which a visual clue can be seen. Turn the page and "Peek a MOO!" reveals a black-and-white cow; "Peek a BOO!" a green ghost; "Peek a ZOO!" a crowd of animals including an elephant, giraffe, zebra, etc.; and the final puzzle, "Peek a YOU," has a mirror insert. Vibrant colors with plenty of black outlines make this a charming visual treat for the youngest patrons.-Lisa Falk, Los Angeles Public Library Copyright 2000 Cahners Business Information.
