I keep giving the Amber books to all my HP friends in hopes of making converts. Amber and Magic University are the two tiny fandoms I try to convert folks to all the time.

Speaking of, read MU if you haven't. It's like HP for grownups and it has Amber influences in it, too! I have plot bunnies in waiting to write more Amberific MU stories, and someday I'm going to cross all three fandoms. Because really, it needs to be done.
