Gr 1-3 One midnight, after calling ``cuckoo'' 12 times, The Cuckoo-Clock Cuckoo flies outside of the house to play with a ghost. When he attempts to return to his clock, however, he finds that the door will not open. Thus begins a 24-hour adventure, as the cuckoo explores the unfamiliar world outside his clock. This picture book places a number of obstacles in the path of very young readers. First, although the text flows fairly smoothly, especially for a translation, there is too much text per illustration for this age group. Also, every illustration is filled with a front view of the Zeitler house, shown in various stages of activity throughout the day and night. People, objects, and especially the cuckoo itself are extremely small; they are completely overwhelmed by the house. Thus, the action of the story is very hard to follow through the illustrations. The method of using a clock in both the text and illustrations to show the time at various points throughout the story works well and would be helpful in teaching children how to tell time. All in all, however, any distinguishing characteristics of this picture book find themselves more than outweighed by its flaws. Deb Andrews, Kokomo-Howard County Public Library, Ind.
