Ah, I try to avoid OCs, but... Sofie's okay (only read a bit through that so far though) I s'pose... you might want to try
this, it's almost a weird kind of meta fic, basically all the characters are part of the Sherlock fandom and write fics/do fanart based on the stories and the 2009 film, but 'cause they're the BBC!verse they don't... okay, it's hard to explain, but... you probably want to read it a some point.

(On a side note, the general quality for this fandom is actually quite good actually, I was looking for some post-Reichenbach fics earlier (not many on rec lists yet so you've got to look manually) and was pleasantly surprised, most of it's J/S slash or pre-slash though~).
