This one isn’t due out until November, but it is available for pre-order. I didn’t see a listing at Amazon.uk, but I’ll add it if/when it shows up. Looking at the other works by Anne Gracie, I’m guessing this is a historical romance based on the series.
Thanks to Kathy for emailing me about it!

I got an email from the author with more info on the book:
“I just thought I’d clarify, it’s not a historical romance and nothing like my usual books.
The novel is based wholly on the Showtime Tudors first series — the plot and the dialogue is substantially unaltered. I was sent the scripts, and asked to “novelize” them – to flesh out the historical background, and make the story come alive in a different form. That’s why Michael Hirst’s name is on the cover with mine — it’s his story, really. I just changed the form.
It was my first time writing a “novelization”, and I found it a fascinating process.”
Thanks for the info Anne!
