Fic rec: Master and Commander and Zombies, by anon

There's no way a fic with this premise can't be crack - in the sense of it being a weird idea - but this is very well done; frightening, and remarkably sad (since, unlike zombie movies, we already know and love the characters). Jack and Stephen deal with a horrible plague of revenants which has devastated the British Isles, as well as the terrible strain it puts upon their friendship. Character death, and some very unpleasant moments: but had O'Brian written about zombies, it might have looked like this.
