I feel I should warn you this is one of my hobbies I will post sporadically, that is how I write.
I might have four or five chapters already done before any of them are posted.
A friend talked me into getting some of my stuff out there for others to see, so I could get feedback.
I would honestly prefer to list off writers I enjoy instead of talking about myself.
If you haven't read anything by these authors, then you are missing out on some great fan fiction.
Here are just a few off the top of my head.
Devje & Clom
mute (smut, smut, smut)
Beyond Dreamer(or Vina I believe on other sites)
most of the work listed is on other sites.
Patricia L Givens
B. L. Miller
Zee and Windstar (Most of their work is original. I just lumped them in with Xena.)
I am sure I missed a few great fanfic authors. I will add more at a later date
Collete Moody: Original Sin
Chris Anne Wolfe: Shadows of Agar
George R. R. Martin
and many more
