I think it is more implied that she is a future assistant, and the get much more romantically involved than some of the previous assistants have, although i'm not sure about the book she has. I assume they spend a fair amount of time together as she knows how to pilot the TARDIS better than the Doctor himself. Also, she mentioned that the Doctor didnt teach her how to pilot it, so it may mean that there is another Time Lord to be found somewhere. It is all rather mysterious.

I was waiting for the killer episode to make me properly like the new doctor, and i think this was the one.  So far the stories have been a bit boring compared to previous seasons and this episode has improved it, although i was pretty annoyed with the BBC's cock-up with the banner for Graham Norton over the most dramatic scene in the episode.
