Both fics won "Best Crossover", "Best Portrayal of Buffy", and "Best Portrayal of a Villain" at the Crossing Over Awards (the first last year, the sequel this year). They deserve the awards. I honestly think that, together, they make the absolute best genfic I've ever read. I'm not even sure I'm exaggerating on that.
You should go read them--even if you've never seen anything in either series.
Far Beyond Normal
Buffy did not survive her confrontation with the First. Fortunately, Buffy has never been one to let death stand in her way...
Return to Normal
Buffy wants another shot at the First. Not everyone thinks this is a good idea. Especially since the First knows she's coming.
