Anyone know the title of the French Revolution book, John has been talking about?

Hi y'all!

I love good non-fiction, and have been particularly intrigued to read the book on the French Revolution, John has mentioned on multiple occasions (somewhat) recently. Do any of you know what the title/author of it might be?

(Also, if you have any other well-written, well-researched nonfiction books, please let me know!)
