I was writing a bit recently about collateral damage and aftermath. Interestingly, the current story at Strange Horizons is called (appropriately enough) "Aftermath" and deals with what happens after a zombie apocalypse, and a cure. It is thoughtful and decently well written. Although I still don't care for stories about zombies, I liked t hat the author considered what it would be like to put all the pieces back together after, and the psychological implications of everything. You can read part one here and part two here if you're interested.
