I just read the whole thing in about 3 hours.
I didn't have anything to say about it at first, but reading the comments here did make me think the ending was a bit rushed, looking back. Didn't stop me from enjoying it though. Part 2 had made it a bit hard to breathe at a certain point, but I made it through without suffocating, heh. Had to take a small few minute break before getting to Part 3 though. Couldn't chug through all of that without giving myself a chance to rest.
I give it a 10. If there is anything that anyone can say that might ever possibly make me lower this score, I can only lower it to a 9.
This is one of the only tragedies I've ever read through, but this one is probably one of the best ones I'll ever read.
Found this through a video on The Horizon that popped up in my Youtube Recommendations, then went to check the author's other works, and here I am. No I have not read The Horizon yet, but I can only assume from everything I've heard that it's just as or better than this.
