I have never read her, court fiction not usually to my tastes, but I was taken in by the story of the Grey sisters in Elizabth Fremantle's Sister's of Treason.
The author's website (her name dot com) is a wealth of information for bookclubs. I appreciated seeing the actual paintings of the subjects of the story. It made it more realistic.
How about you? Do you look for more information when you find a book you like? Do you enjoy royal court fiction or not?
