The End Is... Well, You Know How This Goes

So this was a neat concept.  Three collections of short stories, the first collection set to the lead-up to the apocalypse (whatever form it may take), the second collection being stories during the apocalypse, and then the third collection being after the apocalypse.  And, on top of it all, a good number of the authors wrote three stories, giving us a few linked trilogies within the triptych.  All in all, it worked out very well.
