Title: Destination Unknown
Author: Yahtzee
Pairing: Buffy/Giles, Angel/Cordelia
Spoilers: S6, possibly 7
Summary: When Buffy comes to England, ostensibly to get Giles' input on a mysterious crystal, the two are forced to confront some difficult truths about their relationship.
Link: Destination Unknown
Why: Because this is quite literally the ONLY Buffy/Giles fic I've ever read that made the pairing work for me, and considering how much I generally don't like them as a couple, that says a lot about the fic.
