When The Wheels on the Bus, by Caldecott medalist Paul O. Zelinsky, broke on the scene ten years ago, it created a sensation with its clever characters, sly subplots, luscious colors, and the incomparable flair of its moving parts. Almost a million young readers have enjoyed the wheels that go round, doors that open and shut, wipers that swish, people who go bumpety-bump--and much more. Today it remains as fresh and engaging as when it was first published. A dazzling, updated cover will herald the book's tenth anniversary and help introduce this watershed interactive book to a whole new generation.
