I started reading your first chapter, and I have a few thoughts.
First, beautiful prose, rich vocabulary, very interesting subject. You start with a great hook - someone is dying and we instantly know something interesting is about to happen, or we won't have a book at all 
Now, on to the constructive criticism: This sentence structure ( with all the short sentences) can be a stylistic choice, but it also distracts from the story. When you read it out loud, you will notice that the cadence always comes with a stop, like someone is telling the story out of breath.
I will subscribe to it, and read more so I can give you feedback on the plot as well, but I think you're really talented, just need to find your style ( or adjust it a bit, to make it easier to read)
