When I am finally able to give you The Complete Works of Maya you will notice that Draco is Jamie and Harry is Nick. It's not clear cut of course, there are many differences, but the way they speak and the way Nick/Harry thinks are really quite similar, especially in her last fic 'Drop Dead Gorgeous', which I believe she was writing at the same time as TDL. I think a lot of people who have read her fan fic get suckered into shipping Nick/Jamie because I've this. I'm all about Nick/Mae, too, though. :}

I never get the twists either. By the end of Lexicon I had figured out that there was something wrong with Nick and it was probably magical, but I was thinking of something along the lines of part of his personality having been removed, as in Robin Hobb. I thought he would be fixed and be ok. TDL possibly has the punchiest twist I've encountered in fantasy. I can't think of a rival at the moment, anyway.
