I read the Other Boleyn Girl and, despite feeling like punching the author numerous times, I must confess that she introduced me to Mary as a person instead of just a name in the list of Henry's mistresses. I had never thought about her or how it must have been like. The situation must have been awkward to say the least, not to mention dangerous. I can now join you in your soft spot for her.
I'll be the first to admit that I really enjoyed that book because of the sympathetic view of Mary (even though it has many inaccuracies). She really was a remarkable woman to be in that crazy family, be mistress to that crazy king and then stand up for herself, marry for love, go to the country. And her children and grandchildren (including that pesky Lettice Knollys) would be court staples.
I haven't read it yet, but I recently bought Alison Weir's (who is my favorite history biographer) biography on Mary which looks fantastic.
The six wives were my first study ever so they're special to me, and by extension Mary got thrown in there. Alison's books are awesome, I swear by them in my research papers, including the two I did this past semester one on those crafty six wives and the other on Isabella the She Wolf.
Princess of France, the last of the Capetians, queen of England who was really awesome but many historians have hurt her legacy so I did my 15 page paper on clearing her name. She's reminds me of Eleanor of Aquitaine without the crazy children but with a crazy husband with even crazier favorites.
There's a tiny sketch in the series Horrible Histories where a man enters a room with ladies and tells them Henry's looking for a new wive. No matter how many times I watch it, I still giggle at their screams of horror.
