It's rare for a story to deliver such a sucker punch with relatively limited page limit however this work achives it in a way one could almost believe it to be effortless (though no doubt opposite is true). A word I would use to describe it would be visceral- dragging emotions, the dread I prefer to pretend are long past me and not current to the surface. That is not negative mind you- I see managing to evoke such a strong emotion in reader something quite amazing. Marvelous work.
