Susannah Dunn's written a couple of books set in Tudor times, one about Catherine Parr, one about Mary Tudor and her latest 'The Confession of Katherine Howard' is due out shortly.  She usually writes about these characters from the view point of others such the main character in 'The Queen of Subtleties' is a confectioner in Anne's household who has a bit of a crush on Marc Smeaton.  It's a refreshing take on historical fiction but can be a little hit and miss, especially as Dunn tends to use modern dialogue but if you can get over that then I recommend it!  I'm firmly of the opinion that the more on Anne the better!!!!

And I can't wait until her book on Katherine Howard comes out!
