They didn't think chapter one sucked, so that's something. :)
Current word count: 144K. I'm writing Chapter 22 now. I think that I have about another ten chapters to go. (Past experience suggests that means it will probably be more like fifteen.)
Deathly Regiment will definitely be longer than Thorn Circle, but for now I am sticking with my prediction that it won't be quite as long as Lands Below.
How quickly I progress from here depends on two things:
1. Whether my betas find any major problems in the first half of the book.
2. Whether I break my Mafia Wars addiction. (Seriously, that game is like crack for people too lazy to play WoW, but Zynga is really pissing me off lately.)
