If you like historical drama or even French history, I would recommend Sandra Gulland's The Many Lives and Secret Sorrows of Josephine B. Series. It's deftly crafted and certainly made me want to reinvestigate my knowledge concerning the French Revolution and Napoleon's rule. Although Gertrude Himmelfarb's book on philosophy did concern the French Enlightenment, and, therefore, the Revolution, it's emphasis was not on battles, but the history of thought etc. I think I might to follow-up and read a couple of the books Gulland provides in her acknwoledgements section.
Months ago when I finished the Harry Potter series, I thought about writing about it, but I think I'll wait even longer. Not that many are reading this, but I would hate to spoil someone's read. Let's just say that I would continue to argue that there is more to the series than initially mees the eye. It is about good and evil. It does have a religious point-of-view. It is overwhelmingly about love and free will. It provides for a jolly good week of reading too.
