Jokingly I say. no relation.
I guess I'd characterize "Aftershock" as a semi-post-apoc story. We never really find out what happened to the rest of the world, it's really localized in the upper Northwest of the US and Canada.
As a good author should, it centers and then draws a bulls-eye on it's characters. There is no 1000 word cast of characters here (no story should have that). Just a pin-point view of a few people trying to survive a major disaster.
dotB never allowed voting on the story, but it is still an SOL Classic.
