This is my favorite fandom event. Mystery Author, whoever you are, I am DELIGHTED that you are participating. I will be thrilled beyond words at anything I receive. Except character-bashing. I am not cool with that.
Anyway, if we matched on...
Suits
Jessica, oh my god. Every time I watch Suits, I'm just like, THERE IS NOT ENOUGH GINA TORRES IN MY LIFE. I also love Donna and how she knows everything. And the puppy analogy. PUPPIES FOR EVERYONE. Uh, on that note, as much as I love the puppy analogy, I'm not really into puppy play. BDSM in general, sure -- the entire USA network tends to lend itself to those dynamics quite nicely.
Criminal Minds
The whole team, I just want to squish their little faces! Prentiss is my favorite, but I really just love the whole team dynamic, and how they each relate to each other individually, too. I am also very attached to the canon relationships, so if you're writing something not-gen, please don't break up JJ/Will.
Vorkosiverse
Uh, okay, so...I am new to the Vorkosigan Saga. I've read almost everything through Diplomatic Immunity, at the moment, and I've loved every book so far, except for the TRAGIC LACK OF CORDELIA. I would absolutely LOVE to see more of Cordelia's time on Barrayar, especially her adapting to Barrayaran culture (and Barrayaran culture adapting to her).
Supernatural
I love Bela. I realize this is not a popular fandom opinion. I don't care.
Anyway...if you lose interest in what we matched on, or you just want to write in multiple fandoms, I lurk in another dozen or so fandoms, including Buffyverse, Lost Girl, White Collar, Stargate (SG-1 and SGA), The Vampire Diaries, Farscape, Merlin, Star Trek, and X-Men: First Class. I read and write het, slash, and gen.
