two words: holy ****
i've never read anything like this before... seriously,
the plot is very well thought out, i don't know if it's because I'm reading this at 2 o clock in the morning, but i can FEEL the pain, the anger, and the
darkness of your writing,
the level of gore is awesome, almost intimidating, and DEFINITELY not for the faint of heart...
i've personally read a lot of fanfics whose authors rate as R, and don't reach the expectation of an R rated fanfic...
this one surpasses it,
i feel that the whole killing the mother was a bit out of nowhere, but i'm positive it'll make sense in the next few chapters, and i couldn't find any spelling or grammar mistakes in your writing (wasn't really looking though, i'll go back and check)
all in all, i'm VERY pleased, and look forward to more of your writing :D
EDIT: I went back and re-read it and it was STILL AWESOME!
Fear and pain were overtaking every sense his body had. Everything was happening in a terrible red blur. Then, as quickly as it had begun, it stopped. The Noctowls looked satisfied and flew off back out the window and into the night with beaks covered in gobbets of Samuel's flesh. Except for the one that had laughed. That one was still sitting on Samuel. Taunting him almost.
this is the only thing i found, technically speaking, "Taunting him almost" is not a sentence, therefore, i would go with a comma rather than a period, but i'd understand if you tell me that's too harsh :D
again, can't wait for more!
