I think this book was good cause it taught you a lot that you might have not know.for example I never knew who knew how fire was made until know. I also didn't know how a bicycle was made until know. I also didn't know how people harvest food a long time ago when there was no electrics until now. Also I learned how people would go to war a long time ago. That's why I like this book.
