The world's longest maze in a book! A-MAZE-ING. Not just a maze--the book itself is a maze! A portal opens on the front cover, and the maze continues through every page, making this the world's longest maze in a book. Every spread is a journey through an imaginative world: there's Robot World and Butterfly World, Ski World and Underwater World, Dragon World and Skyscraper World. Filled with hypnotic details, hidden surprises, fun facts, and bright, swirling, richly-colored details, every page is a compelling adventure.
