Angelology at its finest!
I absolutely love the idea the author has for this story, it is very planned out and thought out.
However as stated in the comments the beginning is a bit confusing, there needs to be a slow introduction to this world and I had a feeling of being thrust into it, not knowing who is who and if the narrative is in first or third person.
Other than that the story is awesome, well thought out and the writing style plus grammar amazing.
But like I said it needs a bit of tweaking in the beginning for the readers that have been suddenly thrust into the authors universe.
This could be a great novel, it has lots of unique ideas, the author is very versed in demonology, lore, bible and ancient historical facts. I cannot wait to see how it shall be improved :)
Good work author!
