What is a good book that helps explain our American history easily and in a way teens can understand?

I want to find a book that is an easy way to learn about American history. I want to be able to learn about the important events that happened in our history.

You can try one of these books:

The best book ever written on US history is "People's History of the United States" by Howard Zinn. I read it back in high school, and it made me want to be a historian.

What's great about it it that it's a bottom-up history of the US, told from the point of view of ordinary people: the native Americans, workers, immigrants, rather than all Presidents all the time.
