I found this on Fanfiction.Net and it's the first Jazz related story I've seen that wasn't written by someone in this community. (At least, I don't recognize the person, writing style or story itself) It doesn't take pains to make itself fit in the Jazz continuity, is somewhat depressing and the author can't seem to spell Devan's name right, but it may be worth a look. As for content, it's probably nothing that couldn't be posted in our War Tavern, except for maybe a slightly graphic death near the end, but I don't make any guarantees about the author's other works. (I skimmed a couple other of this writer's stories, and this was the least disturbing story of his/her's that I saw. (I'm guessing "her")) The story actually seems to have shades of Violet's "Freedom" story as it peers into Devan's motivations a bit. It also makes the rabbits seem less innocent. Finally, it hints at one of the oddest pairings in the Jazz universe I've ever seen. I guess that's about it...oh, right. A link.
