Wow, this book challenges your mind! I've had sooo much fun with this book, I'm anxious to buy more. I thought, "how easy this is going to be to find 6 or 8 things," but it's not. People of all ages will enjoy this book. Leave it on your coffee table and your friends will pick it up and get hooked on it.

My son loves the entire I Spy series so it came as no real surprise that he was excited to get this book. I like the idea that the puzzles are challenging even to an adult and cannot be solved in mere seconds. They take a certain amount of concentration of the part of the child but not so much that puzzle becomes so difficult that they want to quit.

The book is both challenging and interesting to all ages. I also like the size of the book and that it's a hard cover.

I like this I Spy book best of all. Not only does it have some of the best scenes from some of the previous I Spy books, but it also has some cool new riddles. Various scenes include "Rainbow Express" From I Spy Fantasy, "A is for..." From I Spy School Days, and "Baking Cookies" From I Spy Christmas. I read this whenever I feel like I need to pass the time because it is so much fun looking for things. Overall, 5 Stars. If you can find this book, buy it. It is top-notch fun!
