Since this was an anthology, I will do a review for each story.

His Black Tongue: 1/5

The titular story, and the worst one. I was hooked with the summary, the concept was incredible, and then it delivered absolutely nothing.

Everything is told, not shown. Our main characters come from outside Enfaire, but except from some detached descriptions of the plague outside, the show no reacting from what in their eyes should be a bordeline apocalypthic situation, the are so apathetic about everything. Everything they see is "horrors" and "gates of hell" and whatever but it feels so flat.

Rami, our saintess, in so annoying. Her process of becoming a saintess reads like a shopping list, and she doesn't feel too virtuos in general. She started spitting accusations with barely any proof and believed herself to be Sherlock Homes for how sure she was of her findings. (And talking about anoachronisms, the characters use the word "resurrectionists", which is a term for body snatchers coined in the 18th century, not the middle ages.)

Pierre is as interesting as a cardboard. That's it.

This story is religious horror in the same way the Ao no Exorcist/Blue Exorcist manga is religious fiction, which is "not really but I guess kinda yes". They throw around the words Inquisition, saint, prioress, hell and devil, but at no point is faith, dogma or sin a real part of the plot. You could say they chose a christian aesthetic for an otherwise empty story. And no, no matter what the summary says, their faith is never "tested". Not even the smallest interrogation symbol, let alone a test.

The dialogues of our villain seemed taken out of some corny kids show, they would be funny if they weren't so cringe. And the fight scene was so boring it felt eternal.

If you liked the summary, just stay there and do not read the book, that summary did a better job of what the story was trying to do than the actual story.

The Bone Fields: 2/5

Interesting concept, better writing than the previous story, but the author's writing is so monotonous that even when there was stuff happening, it was boring to read. The ending was cool, but the rest was average.

The Knights of the Non-Euclidean Table : 1.5/5

Before talking about the story, let's talk about the title. "Non-Euclidean" is actually a fairly simple geometric term that horror authors love to throw around because they think it sounds like something beyond human comprehension. It's not.

Take a basket ball. That surface is a sphere. Can you comprehend that? Yes? Congrats, your human mind was able to understand a non-euclidean surface.

When authors do this, they tell me they just use words they think sound cool without having any idea of what they mean. That's lazy, and it makes the whole thing look stupid. Like what were you even trying to say?

Maybe they were trying to make the story actually lovecraftian, because turns out just adding a monster with tentacles does not do the job. The story was still boring. A lot of build up that did nothing for the tension, for a whatever resolution.

Necropolis: 3/5

I know, I was as surprised as anyone reading this review that I actually liked this story. Simple, an actually eery world building, the characters were very likeable in the short time we had with them, and the story didn't over extend beyond what it had to offer. I feel bad having this at the end of maybe one of the most pissed off reviews I have done.
