This is a really fun book!There are different clues and puzzles on each pair of pages which in the end lead to the treasure.I'm glad I preread this one and determined it would be too long and involved for a bedtime story.While my 4 yr old got a little bored with looking for clues 3/4 of the way through (he had a board game nearby he wanted to play) we made it to the end and had fun with the different puzzles, especially the maze.Would be easier and possibly more fun for a slightly older child, although I loved the idea of this one and hope to find many more like it.
