Moonlight Composition for Two (Binns/Pince)
Yes, I said Binns/Pince. I started reading it out of desire to see what the author could do with such an oddball pairing, and fell in love with the story. Just go read the damn thing, all right?
Rowboat Against a Dark Sky (Neville/Luna)
I'm not really into this pairing in general, but this is beautiful and sweet, with great descriptive writing and odd Luna-ish thoughts and hotness.
Three Men Who (Probably) Never Shagged Hermione Granger (Charlie/Hermione, Oliver/Hermione, Cedric/Hermione)
I totally know who wrote this, or I'll eat my hat. It's hotter than hell, it's funny, and the ending made me sniffle.
I'm way behind on the fest, so there's plenty of good stuff I've missed, I'm sure.
