Have you ever read an EXTREMELY good, well written fic...that turned your stomach-literally. What the fic and why did you react that way also why did you keep reading?
Mine is TJ Goldstein's Merely a Possession Series. http://www.xanderxtreme.com/sub/sub_T-Z/tj.html
It was so well written I kept reading even after it got WAY to much for me. The things that happened to Xander in this series...Dark doesn't cover it. We are talking Darker than Dark, Pitch Black darkness. But the writing and imagery are so GOOD, Thick, and layered with meaning...
If you like very dark fics - READ this series. Warning - if you don't like very dark fic , stay far away.
