Ok, so I've just read Midnight Nation for the first time. Now I know why so many people said it is so good. I have a stupid quesiton. I got it form the library in TPB form, and it has issues 1-12, and 1/2 (or somethign like that). But on the binding, it said "Midnight Nation Vol. 1". Was there ever a Volume 2? Was it done and never collected? Or is that just an "In case we ever come back to this story" Volume number?
