BSG: Intra by Kate Andrews (Kara/Lee)
There's a sort of house style in BSG fanfic already, all present tense minimalism with certain lines (over-)calculated for dramatic punch, and it doesn't always work for me. But svilleficrecs makes it work in Intra, which fills in some backstory for "33." The prose is unadorned, a bit rough at times, but the story takes a good long look at the characters and their memories of the time before in the midst of the hell they're currently going through.
