Books on the American Revolution?

I'm looking for recommendations for books on the American Revolution--both the political and social aspect and the war itself. Different books that are appropriate for various age groups, would be really appreciated, if anyone knows of a good picture book, elementary, middle school, and high school novel or nonfiction. Historical fiction and biographies concerning any of the prominent events or figures (George Washington, Thomas Jefferson, John Adams, et al) would also be great. 

Thanks in advance! You guys were really helpful in my last request for recommendations. :)
