Okay, first, I have to admit that I now have yet another pairing that I like in the HP 'verse. H/S didn't interest me until recently, and now I keep finding lovely pieces that are for the most part very well done. Slight plot holes and characterization issues aside, I am really liking this pairing. That said, if you haven't read
Parseltongue-tied by DementorDelta, then you really, really should. Her Harry is much more believable than most post-Hogwarts ones I've read of late. And her Snape is positively yummy.
