This was very hit or miss for me. The stuff that I liked I REALLY liked, but there was just too much that didn't do it for me. The whole appendix, though a nice idea and great worldbuilding, had nothing that really intrigued me. Still a big recommendation. A lot wasn't to my personal taste, but there is so much interesting in this, be it story-wise or artistic choices, that it's worth to take a look at.
