Definitely mark me as interested in this too. I'm in the same boat you're in Andy, as I read all three in audio format too, so have no idea how to spell all those strange names! And I'd have guessed Aria was spelled that way too, like it was being pronounced. I need to reread the first three books, and hopefully I can get access to the fourth one when it comes out. I think I actually need to replace my copy of the second book, as the download I got it from had a few bits where it skipped around some, but I'll see if I can't track it down. I'm definitely interested in this though, although I have no ideas as to a character yet.
