I noticed I was getting a lot of hits for my post on the Criminal Omnibus the other day. Another popular link about the book was the Jinxworld forum where it was pointed out that it was normal to have an order number in advance of the printing date to have everything ready, and suggests going ahead and ordering it now. That's what I plan to do, unless I hear otherwise that would suggest waiting.
I would think this much interest in the book would bode well for it.
