I read a pretty good one on timebomb2000.com. The "event" was earthquake, volcano rather than EMP, but the survival and such was similiar to Lights Out. Shattered and Deep Winter were the two parts to that.
One of these days, I intend to try my hand at a "post event" yarn. I need to wrap up some open projects. (Hah, "wrap up"--that's very optimistic of me.)
