I'm sure someone here has read her books.  I see she's written a couple about Anne Boleyn and Elizabeth I.  Are they any good?  Considering my facination with the Tudors, I'm surprised I've never read anything by her.

I haven't read her. I'm not particularly interested in reading about the Tudors. But here's a thread at historicalfiction.org that might answer your question.

I've read a couple and she's ok......I'm trying to remember which I've read and I can't!  I've also got a couple in my tbr.

Virgin: Prelude to the Throne is about  Elizabeth I as a teenager princess in constant danger due to among other things, her liason with Thomas Seymour, her step mother's husband. I liked it better than Queen's Bastard or Secret Diary of Anne Boleyn. Her writing style is fair and light and I enjoy the subjects she covers, but I have enjoyed other HF authors more.

If you're a big Tudor fan though, then I think you'd like these.

I've read two of her books - To the Tower Born (about the princes in the tower) and Madimoiselle Boleyn (about the early years of Anne Boleyn while at the French Court.)  To the Tower Born was just OK; I enjoyed Madimoiselle Boleyn.

I've read all of her books and enjoyed them all - some more than others.  I would recommend her if you do enjoy Tudor fiction.
