Are there valuable prizes? NO! But each correct answer gets you one ficlet. In other words, if you correctly guess one story, then you can throw me a prompt, a pairing, a character, a scenario, whatever in a fandom with which I'm reasonably familiar, and I'll write you at least a hundred words of it. Two stories, you can throw me two prompts, and so on. If you guess every story I wrote, you can get ficlets -- or you can trade them in on one story of at least a thousand words in a fandom with which I'm familiar. Think of it as an extra bit of Yuletide cheer.
I wrote five Yuletide stories. Every single one is over a thousand words. A lot of you guys will have at least one gimme. Y'all know how I think and you know how I write. Go to it.
