This is a nice little book that goes over the history of the universe from a high level perspective. It's a good refresher for adults but would be great for tweens who are interested in history and science. Even adults will learn some fun tidbits. One thing that stood out is how much we don't know and how outlandish some of our theories are on how some things came to be. For example, one that stood out is that monkey got to North/South America by floating all the way across the Atlantic Ocean by floating on a log.
