Rating/Warning(s): NC-17. The incest factor here is minimal but still an undercurrent for the story. Also underage teenage hanky panky.
Genre: Coming of age
WIP?: no
Why This Must Be Read: This is no simple genderswap fic where a character is turned into a girl as a result of a curse or for kicks or whathaveyou.
Sam has always been my favorite Supernatural character, and her characterization in this is astoundingly good.
Honestly, give it a shot. I'm pretty touchy about the incest squick, and I feel like this fic explores those complicated feelings in such a smart, careful, and thoughtful way that it comes across as entirely believable. Not only that, but the language is gorgeous--sparse and perfect.
