One of my Favorite AU, I recced this one to every one I know and every single one of them loved it! What I like about this fic is it's cleverness and creativity, it takes the basic elements of the show, tweaks them up a
bit, and what you get is one hell of universe. This one is a must read in my humble opinion. And Helen is one hell of a writer.

This is one of the BEST X-Files I've ever read till this day! It's just perfect! I was amazed the whole time I was reading it! LoneGunGuy is known for his X-Files, but this time he had outdone him self. Chris Carter should
read this fic, he can learn a thing or two from this amazing author.

I can't describe this fic! I really can't! if I tell you what it's about you guys will laugh at my face! That was my reaction the first time I heared about it, but you know what, it works! I know I'm being evasive, but I don't
want to spoil anything for you guys. Trust me, this is one of the weirdest fics you'll ever read.

This Post Colonization fic will break your hearts! I was sobbing the whole time while reading it! It's a beautiful tale about true friendship and loyalty. This is how post colonization fic should be. This is how it'll end,
not with a bang, but with a wimper.

I stumbled upon this novel one day by accident. This one is a diamond in the ruff. I've been looking for this kind of fic for a long time, and it was every thing I was hopping for, and more! Read it, you won't regret it!
