Oh, it is SO BAD. Seriously. The protagonist made me want to vomit, she was such a Mary Sue. I mean, of all the English monarchs to have an illegitimate daughter, HENRY VI?!

But, if you're still curious, it's The Innocent by Posie Graeme-Evans. Not only did she manage to publish it, she even succeeded in publishing a sequel where said sparkly Mary Sue has badly-written sex with Edward IV on the floor of a church in Bruges. I DON'T MAKE THIS STUFF UP. Alas.
