Historical pseudo-fiction books for adult
I've been searching a book for quite some time now and decided to turn to you for some help. Are there a few books with historical figure in witch there are some adult scene described? Growing up, I've always been interested in 17th-18th century and, now that I'm older, I would like to switch the reading a bit. As such, I would mostly be interested in book from that era even though, at this point, something out of those boundaries wouldn't be that bad neither.
As for the "pseudo-fiction" in the title: I really don't mind some liberties. For example, having something happen between Marie-Antoinette and Count Fersen even though there are no evidence to support it.
Thank you for your help.
