I'm looking for fanfiction involving characters that have changed gender through magical/supernatural means and the trials and difficulties that this change causes in their lifes. Fics with "normal" transgender characters are acceptable too, though those are much rarer.
In particular I want serious fics that focus on the psychology and other mental aspects of this change. In essense, fics that deal with gender identity, sexual orientation, confusion and ignorance of social gender roles and mores, ect. Basically, all the psychological baggage such a change would entail that Ranma 1/2 mostly ignores for the sake of comedy.
For a good example of what I mean, check out Returning Echoes, a Fullmetal Alchemist fic by silkendreammaid. In this fic, set four years after the movie, Alphonse finally finds a way to bring Ed home with alchemy, but the Gate demands an strange price for this service - it turns Ed into a woman. Although Ed mostly accepts this change (it's better than being a suit of armor) it causes her a lot of problems - from dealing with sexist alchemists opposing her becoming the first female state alchemist, to dealing with her confusing new feelings for Roy.
Thanks in advance for any suggestions!
