I'm going to assume you've read Tarowen's popslash Au "Talliswood" - the very definition of long, juicy, plotty.Found here if by some chance you havent read it: http://www.angelfire.com/boybands/druid555/reunion.html

Then there's this one: http://www.angelfire.com/boybands/druid555/reunion.html

It's Xander/Spike yes, but it's also Oz/Eddie Munster. Xander discovers he's Marilyn Munster's son. Not angsty but damn funny.
