On every page of this book, you are challenged to seek and count, to study the treasure map, to use logic and observation, and to follow directions to find the clues and ultimately the treasure. The book is written in a comic book format, with lots of very detailed illustrations. My 6 year old enjoys me reading the book to her, as she solves the mystery; an older child would enjoy reading it for himself and unraveling the mystery. Each challenge is answered as part of the story on the next page. My daughter has enjoyed it so much, that now I'm buying it for all my neices and nephews.
