Sorry if this letter turns out to be a bit late - sign-ups caught me a bit unexpectedly this year.
If you followed the link in your assignment, it should have taken you to my fandom:yuletide tag, which has author letters going back years and years, which is convenient, because vast swaths of this letter are cribbed from previous ones. Nearly everything in my journal is unlocked - feel free to poke around.
First things first: I am not picky at all. I'll read and enjoy pretty much anything, as long as you punctuate your dialogue correctly and double-space between paragraphs, and I only pick yuletide fandoms where I'd be delighted with anything at all in the fandom, so if you don't want any more information, you are encouraged to stop reading now. If you write something you enjoy writing about characters you love, I know I'll enjoy reading it, too.
If you want more advice: I have a list of 101 Near-Bulletproof Narrative Kinks which you are more than welcome to mine for ideas. I am also a sucker for crossovers of all kinds, and no, I don't particularly care if I know the other fandom(s) (though of course that helps.) I've also been rather mooning over AUs of all kinds lately - not sure what that's about, but there it is - so if you have an AU idea, no matter how far out, go for it! Of course if you want to write something perfectly canon-based and sedate that will also make me happy. Slash/het/other/romance/gen; explicit, non-explicit, kinky, vanilla, cracky, realistic, humor, character death: it's all good.
I am also hereby volunteering
Here's some more about the fandoms I requested:
Miss Madelyn Mack, Detective: I'd love a Madelyn/Nora story. Or a Madelyn, World Traveller adventure. Or a Madelyn & Nora casefile. Or something with Madelyn and Nora and Thorny, which is fascinatingly complicated. Or anything with Ariel and Jacqueline - femmeslash, backstory, character vignette, suspenseful shenanigans... or a Sherlock Holmes crossover, or a crossover with anything else, or something during the Great War, or something steampunky, or any AU, or, well, anything really.
( Meet Miss Madelyn Mack )
The Adventures of Lucky Starr by Isaac Asimov writing as Paul French - I would like Conway/Henree fic, please! It doesn't have to be romantic/sexual (although it would be nifty if it was) but I mostly just want a story about Lucky's two dads and their relationship. Them as working fathers, or their POV while Lucky was with the Sirians in the last book, or Bigman's POV on their relationship, or Conway/Henree/Science, or just a romance vignette, or something about how relationships actually work in that society, or something when they were young with David and Barbara, or anything with them really!
( Meet Hector Conway and Augustus Henree )
QI RPF - I would like something with Stephen and Sandi being adorable and clever together. Or something where you take a one-off fic-bait comment from one of the episodes and take it seriously. Or an AU that brings everybody into a different setting. Or best of all, I'd like an AU based on that conversation from the Girls and Boys episode where Stephen and Sandi are in a marriage-of-convenience, but honestly, anything would be great.
( This is Quite Interesting, tell me more )
19th Century Civic Allegory - This cries out for kinky f/f featuring Justice with her blindfold and sword and Liberty with her shield and shackles. But something fluffy with those two would work, too. Or something with History, who claims to be straight but is bent for Justice. Or Progress, with her spinning ball, who has all the best toys. Or any of this bunch. Something where you bring in political or historical events on Earth would be cool, but so would something that just plays with the personalities and/or femmeslash possibilities.
( Okay, let me tell you about this fandom )
ETA: Oh, and I should mention that I am very probably going to be AFK around the time the archive opens and/or reveals happen - I will make sure to get on at some point between Christmas and Epiphany, but I might not be on right away! So please don't worry if it's a few days before you hear from me as your recipient.
