The good: Neal Stephenson has a new book coming out!
The bad: It's 1000 pages long!
I actually have no problem reading monstrous door-stops in principle. It's just that I've found that all too often in order to read a really nifty 300 page novel, I'm forced to wade through a 1000 page book. Seems to me the longer an author's been around, the more they benefit from an editor. Unfortunately it seems the reverse is the truth in practice.
