I finished last night after reading the whole series over the last few days. I decided when they started to publish again to wait until I had all the books (I needed to re-read the first 8 issues anyway to remember them).
It really read great as a whole GN. Some here complained about the big reveal being big enough. It was for me, but that is almost beside the point. I think this was mainly about the characters. About how they adapted to their new world. There were many touching moments and I especially like how the Reporter and the Black Widow (who i thought would have a tragic ending) found each other.
I don't know if there are plans for more books by JMS, but I would buy a Fire and Shadow series.
And I can't say enough about Chris Weston's art. the amount of detail he puts into every page, every panel is amazing.
As someone who is beco0ming more and more disinterested in the main stream super heroes the big two are putting out these days, books like this remind me of why I love the medium.
I was a big fan before the lengthy delay. Maybe subconsciously I just lost some of my interest/fondness by the time it came back and wasn't pulled into the world as easily.
