Okay so first things first, new fandoms:
This Means War, Heartland, Shadow Falls Novels, Starcrossed Novels, Snow White and the Huntsman, The Client List, Alcatraz, Awake, Don't Trust the B---- in Apt 23, Land of the Dead, Breakout Kings,
Survivors (2008 series), The Avengers ('12), Avengers Comics
---and i think that's it.
Not exactly sure when the next round will start, but I will be adding more prompts to some of the lesser used crossover fandoms - help/suggestions for prompts would be great, as always you can comment on the latest mod post (ie. this one) or the FAQ entry.
