Heya.
I'm an aspiring writer who got his start with BtVS fanfiction; and I'm still writing it. I usually try to write a short story and end up with a novel instead. I'm a fan of the Buffy/Faith subtext theory, and most of my stuff is at least subtley slanted in that direction.
My stuff tends to be (but isn't exclusively) dark and violent, and I strive for as much realism as possible, given the subject matter.
So. If you want to read some serious material about Faith and Buffy, I'm your man.
