The Devil Inside: Faith/Sam by PatriciaLouise

Nobody likes the Powers That Be, especially when they meddle. Faith is plucked up by them and plopped down in a new world that's facing the Apocalypse, Biblical style. She's been charged to "play an important role." To Hell if she knows if that means she's supposed to stop it or whatever. Oh, and the center of the action? A hunter named Sam Winchester who takes it upon himself to rid Faith of her "demon." Now in a new world without her Slayer strength, what kind of role could she ever hope to play?
