I have read that one biography of William and Mary together, it is pretty good. Then, there is one of only Mary, it is kind of boring, but not awful. I once read a biography of Anne, but it wasn't very good, it just went through all the stuff I already know, not in a very original way, either. I can't remember the title of that one. I am not even sure if there are any biographies of Mary of Modena, I wish there were though.
