Swan Maiden by maery
Based off the old Celtic legend of beautiful women who could change into swans at will via thier magical cloke of feathers. Sometimes men would sneak up and steal the magic grab as they bathed to keep them as wives. But not this one... she still lives out in the wild, beautiful and free.
I like this one, even though she does remind me of the Child-like Empress from The Neverending Story.
