My son is completely and utterly transportation-obsessed. I knew he would love this truck book. If I was rating it it would receive only 3 stars, but he'd probably give it 5, so 4 splits the difference.
The illustrations are computer-generated graphic design, often from unusual angles. I actually like the illustrations, and my son does, too, although I don't think they would appeal to all children. I find the text a little blah, but it makes for a quick bedtime story.
My husband drives a red truck (although it's just a pick-up, not a semi) and my son says "Daddy! Daddy!" on every page of this book. It's very cute. This has been his most-requested library book for the past couple of weeks.
