I liked this book pretty well. Of course it didn't have a plot, but it was still enjoyable. I think that Ken Jennings himself thinks like a kid. I don't know any other author who can or does that. I like the facts that: 1 it's about dinosaurs; 2 It was written by Jeopardy! champion, Ken Jennings; 3 Ken Jennings is good at explaining things. This is how I liked the book...

Again the book has no plot, but at the same time it does, so let me explain. Every "Junior Genius Guides" book starts out with an introduction, for they "pledge" to knowledge. Then it goes to a school-period-based chapter system. The book also has a final exam, homework, lunch, recess, art, and music classes. In first period Ken talks about the evolution up to dinosaurs. In second period Ken talks about the behaviors of dinosaurs. In third period, Ken talks about the physical features of dinosaurs. In fourth period, Ken talks about the advantages of certain dinosaurs. In fifth period, Ken talks about air and water dinosaurs. In sixth period, Ken talks about the extinction of dinosaurs. In seventh period, Ken talks about findings of fossils. That's all the book has to offer. I would recommend this book to anyone who likes dinosaurs (more specifically children). ( )
