This is a tome! A five-hundred page novel which I normally avoid like the plague for the very reasons which led me to DNF-ing this one.
I normally do not trust a book by its cover, because covers are so misleading. Experience has taught me that they're all too often created by someone who has no idea what's in the book, and so the cover has nothing to do either with the author or the novel. This is why I laugh out loud when I learn of some idiot author hosting a big "cover reveal" like it's some spectacular event. I ahve no time for that. I'm much more interested in what you wrote, not how pretty your cover is.
The cover of this novel shows a young woman in armor à la Jeanne d'Arc, and it;s entirely misleading. The woman in the novel - at least as far as I read - is no warrior woman; she's a mystic. Even that would have been fine by me if the novel had gone anywhere, but it never did - not through the first thirds or so of it, which is when I gave up on it because it was becoming tedious to read and literally nothing was happening.
If I had wanted to learn about the dark ages, I would have read a scholarly book about it instead of this one. I don't mind some atmospheric scene setting, but when it hampers the story, it's too much. I don't want to spend my reading time learning how much research the author did! I want to spend it seeing the characters do interesting things, have meaningful interactions, and go to fascinating places. There was none of that here. This character, Hild, was one of the most passive and tedious characters I've ever read of in a book. I'm sorry but no!
