Why this must be read:

It's a very original plotline, with immortal!Xander without all the dreaded no-soul!angst that you have to be in a very specific mood to enjoy. But fear not, fellow fangirls and boys, the angst is there, with Xander not handling his accidental immortality nor his love of Spike very well. Savoy Truffle even said, "I suspect this of being one of my more underread fics, especially considering how much I like it."

So go read it, and make a very good underread fic overread. But not overread so much that it starts to get boring. Just read enough that you can think, "wow...that's... I need to read that again."
