Googling for likely phrases hasn't worked; I keep finding "The Measure of a Man" by Gwyneth Rhys, "In giving, we receive" by Leadlight, "The Big Hurt series" by Lovebitca (how I hate the ending of that story - and how I would have loved it if it hadn't been for the tiny little coda at the end!), and "When Darkness Falls" by L A Ward and Sanguine (voted "most frustratingly unfinished WIP of all time" by 100% of all Kzinti polled), and "The Three Lions" by Lesley (aka paratti); all good worthwhile stories but not the one I'm looking for.
Anyone know the one I mean? Addition: it has now been successfully identified as World's Edge by Antigone4. Thanks, everybody, especially Anonymous and maddeinin.
In other news my neck is fine now.
I spent yesterday evening trapped in my daughter's bedroom by her birthday party taking place downstairs; I was cut off from my computer and therefore I used hers. As a result I started a completely new story, probably a reasonably short one, kicking off from "Dead Things" and going AU from there, and I turned out a couple of thousand words during my incarceration. I also got a bit more done on "Savage Beauty" last night, and so you should see some more fic soon.
