A good old horror story
I'll start with the things I didn't like. As petty as it may sound, editing matters. Chapters that end in the middle of sentence, chapters repeated - you can't have that in a story. That's why I rate the writer's skills with two stars. The writer should sit down and work on it (it seems like he would).
Read the story now
The plot of having ritual killings every now and then on the university grounds seems illogical to me. Imagine that in real life. The university would have been closed. BUT this is a common feature for the whole genre so I get the author is writing within the genre limits, and it's fine.
The author is actually doing a pretty fine job darkening the atmosphere from the beginning with the crow. Enter the crow. Crows, ravens, black birds in general are a great symbol of a pending change, often for the worst. I also appreciate the fine little details throughout the story, some questions the characters ask which are logical to ask, but most writers would not include them in the narrative. This way the writers makes it all the way more believable. Hence the four and five stars rating for everything else.
Had the punctuation, editing etc. been great, it would have reflected in the writing style and overall rating and I would have given it all star rating. I like the story itself.
Please, author, hone your editing skills and let your story shine!
