GOSH! had it in yesterday I believe (as they called me). Picked up my copy today. I've had a flick through and it all looks good. It's kind of a dark volume due to the fact that the first 2/3 is the flashback and then Mark's storm. I need to find the time to give it a proper read, and perhaps even start again from Vol 1.
It reads really well - being able to read it in one uninterrupted session means that jumps between the multiple strands of the story work very well, building tension without feeling in any way disruptive.
From a visual point of view, it's great to get the opportunity to view the pages as double-pages (the sequences of Arkady and KK in the rain work particularly well in this format - the very strong directional lines of the rain work even better when you can see even more panels at once).
