Supernatural: Gen.
So I don’t read a ton of gen in this fandom (or any other really) because I’m OTP enough to prefer to see Sam and Dean be SamandDean, but Trollprincess is one of those authors whose fic is guaranteed to be good no matter what. In this one Dean gets cursed with that ancient proverb: May you live in interesting times. This is almost a five Sam’s that didn’t exist type story and it’s really fucking awesome. The kind of story which would make for a damned interesting episode.
