No, this is NOT your typical F-exchange-student-is-really-mysterious-and-all-that-jazz. I'm serious it isn't. The first chapter is only a excerpt from a textbook, nothing more. A little H/D later on, but it's not going to be in the main plot.
Harry and Draco are forced to work together so they can learn "real" magic. It's just friendship more, but will be H/D later on. The rating will probably go up a notch also. r&r
