Numb3rs Fanfic Finders

Hello all you marvelous Numb3rs fans!

I come bearing fiendish eager little plot bunnies for you. Now, as you may be aware, there are quite a few Female!Charlie fics floating about in the ethernet, and I love them all dearly. But then, one day I looked about and wondered why I couldn't find any Female!Don stories? Is it purely that there aren't any? Or is it just that I haven't found them?
So, here is my plea;
If any of you kind souls know the whereabouts of any stories, please let me know in a comment! Whether transgender or always a girl, I don't mind. Honest.
And if not, well, then I cheerfully inflict the bad-ass joys of Donnie (short for Donna) Eppes on all you fic-minded people, and I hope they grab you by the ears, if neccessary, and pour forth their influence in all it's cracky glory :D

Sweetheart out.
