Got my copy Saturday morning and started reading after lunch. Aside from one break I read until I was done.
When I have some time, I plan to go back and read the whole series again, searching for the clues I missed the first time around. I'm expecting there will be some kind of special edition (maybe next year) that will provide all seven books in a nice hard-cover format. Certainly, if I were a marketer that's what I'd do.
Meanwhile I'm also revisiting the Lod of the Rings trilogy with a reread of that. If a book is good, it's good for reading again.
The whole project is really an astounding one.
