I bought this book because my 7 year old son won the extra crunchy book of fun 1 through the library summer reading program. since the summer he has been hooked on the series and ASKS if he can spend more time reading his books. this particular book is interactive with games and short comics and "draw yourself into the story". I also like the "fill in your own word" sections as well. this is the type of book you need to buy new, because if all the interactive stuff and it came with a few pages of sitckers as well. over all, we are happy witht he purchase.
