Don't let the title fool you. This is not a book just about trucks, it's about going to the fair and many things involved in a fair. For example, going on bumper cars, teacups getting cotton candy ect. Towards the end of the book is when the trucks come in. A rider of the truck has broken his glasses so the hamster saves the day by riding in the drivers place. I felt the story captured the excitment of a child going to the fair, very upbeat and happy. The characters look forward to going to the fair and doing what kids do in a fair.
The pictures are rich and colorful. I feel that even if a child cannot read the book, the child may have fun looking at the pictures and learning what they are. "What's that!?" What's that!?" sort of thing. I personaly like to have a young child, whom cannot read, to point to the pictures and tell me a story of what they think the pictures are about. This is the perfect book for that, and the interesting stories that can be told this way can be very comical and/or surprising.
In closing, I would like to add that the author also asks the child questions. For one example, the characters go on the teacups, and the picture shows six very different teacups. The author writes, "Plain cup, bright cup, checkered black-and-white cup. New cup, old cup, rimmed in shiney gold cup. Which would you choose?" Therefore, the child can pick out what he/she likes best. So if you read the child the story, the chld can get involved with the dialogue. It's a good book. Well done Ms. Lord.
