I seriously didn't think it was possible, but. I found
a Supernatural/Harry Potter crossover. No,
seriously....And it's actually pretty awesome, and not just because it has Sam going rather darkside a few times. Mmm, Antichrist. Also includes Sam fangirling over magic books, Dean telling wizards exactly what he thinks of their shenanigans, and also proving once more that he really would've made a good daddy in another life. Well written and never takes itself too seriously.
Old CountryAuthor: astolat
Pairing: Wincest (eventually)
Author's Summary: Sam and Dean go to Hogwarts. (spoilers for All Hell Breaks Loose, Deathly Hallows)
Set during season three, when Sam's still trying to break the deal Dean made with the crossroads demon.
On a totally unrelated note, I'm really missing traveling through the southern and midwestern states. Eeeeh.
