I didn't really know where to put this post, but I was looking for advice from DC fans.     The advice I need is for all these Blackest night graphic novels that have come out in hard back form.   The main question is are they in some sort of sequential order as far as the story telling goes or does it matter, aside from the obvious vol 1 and vol 2 ones?  
 
Sorry I used Heavyink website because I order my stuff there,  Atlanta is just HORRIBLE for getting too and finding a good store.  
 
I couldn't find a reference to the hard backs here on CV to post and give an example, but basically, it seems to be 6 of them from Blackest Night line.
