Ann E. Berry, C is for Cordy
Let no one say I'm not open-minded. Giles/Cordelia is a pairing in which I have less than no interest, but this is a slow, sexy, messy story of considerable charm. The narrative voice is sometimes a little shaky and there are occasional small characterization lapses (Giles calling anyone "my lady?" I think not), but, oh rarity of rarity in these sorts of stories, Giles comes across as a mature adult and Cordelia as something intriguingly not quite there yet, but still attractive.
