Fluttershy comes out to the rest of the bearers of the Elements as a trans mare. This story follows what happens next: with her, with the mare she's fallen in love with, with the Mane Six, and with respect to their friendship.

This was (and remains, for that matter) my first fic, and was an attempt to apply concepts of transgender identity to Equestria. I felt like a world as accepting of, well, everything as Equestria tends to be would be a fascinating place to explore identity. I hope it worked!

(I wrote this before reading Dash's Secret (by Hopefox), but if you enjoyed this story, I can't recommend Dash's Secret highly enough. It engages with some of the same issues, but is (IMHO) better written than mine. http://www.fimfiction.net/story/1876/Dash%27s-Secret)

A note: "trans mare" refers to somepony assigned male at birth and raised as a colt who comes to identify as a mare later in life. I'm following human usage here.
