It hath occurred to me, quite a bit later than it really should have, that I never posted these links in this Community, of which I am a member!
I've written a couple of stories setting Erica Hahn in a universe I created after she left SGH. The first one ("Twenty-Twenty") deals with her getting to the new place, the second ("The Shadow and the Real") with what happens after she learns of the death of George O'Malley.
"Twenty-Twenty" contains some slightly naughty bits in a later chapter. "The Shadow and the Real" contains nothing naughty.
