Woohoo! I'm halfway there (reading them, at least).

For the tentative quadrivial books, any idea if they'll follow a similar format, or be their own thing?

As to 2, that's what I get for going back and skimming to see if my memory was correct. (narrator voice: it was not) 4.5 years to go, I guess. Assuming I don't step off the path to work on something else for a while.

Thanks again!
