This book is part of the best-selling "Learn by Playing" maze picture book series by Japanese author and illustrator Gentaro Kagawa. The 12 highly detailed, beautifully illustrated, and visually accurate maze designs are filled with quizzes, riddles, and hidden objects to solve the quest. As a child wanders through the forest, they find a pyramid-shaped piece of glass that reveals a mysterious pattern when held in the light. As the child further explores the forest, they find Ancient Japanese Ruins and must reveal what the mysterious pattern means and solve the maze to find the key-to-the-gate-of-time-and-space. Throughout, different keys must be found to enter a new civilization where hidden objects must be found and mazes solved, all to arrive in the Lost City of Atlantis. Each maze.
