I got through the entire 2010 full-length archive in one big burst yesterday, so here are some favourites in alphabetical order by fandom :) Expect more when madness goes live!
Carmilla
Bloody - Carmilla meets Bluebeard. Carmilla ROCKS.
Castle
Acute,
Obtuse and
Triangle - Rick, Alexis and Martha, family stories in the best of ways. Obtuse is the particular favourite.
Once Bitten - Castle. Vampires. And done Gothic Novel Narration Style :D
Coldfire
Parent-teacher conference - the sheer idea of Damien trying to explain Gerald's parenting ways :D
Elisabeth
Die to Live Forever - Lucheni and Death, and just the right kind of madness.
Gazing into the Abyss - I love my Sophie fic the more, the more I re-read it. History geek treat!
The Historian
among some talk of you and me - A vignette with a perfect Vlad Draculea ♥
The Mentalist
What You See Is What You Get (If You're Looking Hard Enough) - The Mentalist as an urban fantasy steampunk AU. A GOOD ONE.
Rose of Versailles
Raindrops - Some of the reasons I'm so delighted with this story must remain secret for now, but oh, it's just what I asked for. Oscar, as played by Maki Ichiro, and Alain, as played by... Stanley Burleson? ;)
Scarlet Pimpernel
The Dress Makes The Man - Percy and Marguerite have way too much fun ;)
V for Vendetta
This Vicious Cabaret - Rosemary Almond and what comes after. There was a feeling of deep satisfaction when I read this. V for Vendetta and female empowerment - why not? (And empowerment in the good sense. Rosemary doesn't want to be a hero.)
Vorkosigan saga
Responsibilities of Command - Miles and Gregor and facepalming, post-Vor Game :D
