Alan Moore's praise for a book was quoted on the front of a dark fantasy novel published sometime after 2020. Does anyone remember the title of the book?

The only thing I remember about the book was it had a white cover (it may have had the black outline of a faun?), it was weird/dark fantasy (I think the opening passage was about a knight or a witch doing a spell) with non-traditional storytelling, and a quote from Moore praising the book was on the cover. Thanks!
