We ordered this book for my 3 year old son who is really into Monster trucks right now. Of course he can't read so he just looks at the pictures, but I have read a few pages here and there during the thousands of times we have looked at it, and it is actually pretty interesting! It discusses the conception of monster trucks, how Bigfoot really changed the whole thing and then how it turned from a novelty into more of a sport. It is a very informative book. And the photos are terrific. As a 35 year old woman, I never thought I would learn about things like monster trucks... but having two sons has changed that idea. :-) This is a good book for any age looking to find out more about monster trucks!
