O, of course I've read that! It was one of the first Oz fics I've found and loved and re-read several times...a real classic...at least in my little world. And it is so beautifully structured...and oh, hm, maybe you already know all that stuff, being the writer who wrote it!
Anyway, thanks for reminding me of that fic, you guessed pretty much right with that! I love that series! :)
