M. Scott Eiland
I've been enjoying M. Scott Eiland's writing for some time now. He has a clean style that gets the point across, paints the mood, defines the atmosphere, and yet manages not to be flowery or overbearing. "Reflections", a post-ep for "The Replacement" is not a dark story, but a lovely character study. Xander ponders his life and his value both as a Charter Member of the Scooby Gang and as a person.
And no, it's not dark. But it is wonderful, and I hope you enjoy it!
