I have a soft spot for Equal Rites, since that was the book I first read all those years ago. I also read them in no particular order, I think I have them all read now and purchased as well so I am going to start from the top, I just had to take a little break to read a little Elizabeth Moon and Anne McCaffrey, etc.

I think that there is more in store for Granny Weatherwax, she probably is training Tiffany to be her sucessor as the "top" witch, even if Tiffany is tied to the Chalk she could be the top witch, I see the witch world as being sort of extranational, maybe even intercontinental. Witches fly over the landscape and they know the boundaries shown on maps are imaginary.
