I'm looking for horror stories (by reason of halloween obviously)
Since we are in the month of October, I'm looking for good fanfics themed terror, violence, mystery, suspense, but adult thematic, in the era canon, no alternate universe please. I'm interested in oneshots (not drabbles) or in a few chapters fanfic, or maybe a long fanfic. Thank you!
PD: I love this couple

I would recommend this one if you haven't read it already.

Devour Prometheus by ladybattousai
~Complete~ Waking up from a nightmare late one autumn night, Kagome discovers Inuyasha is missing, leaving her to embark on a harrowing journey of death and consumption that will fade the line between humanity and youkaikind.

I haven't read that fanfic, but thank you very much for your recommendation.
*minutes after* Well, I'm excited reading the prologue of this fanfic . So, can you recommend me another story?

I'm glad that you like it. Unfortunately, I'm not much for horror/terror, so I don't know many stories in this genre. But, I do remember there was a challenge here by Zandrellia. Maybe you'll find something there.

Scary Challenge

Hallowed Ground by zandrellia is fantastic.
I will warn all of you readers that this is rated MA. No YIMS.

Thanks for the other recommendations. I'll read them. It seems that not all horror fans, but everyone has different tastes. Well, I like love stories also
