Minor spoilers ahead.
One of the major characters is a vampire. The character is introduced as if everyone knows what a vampire is. And it’s kinda true. Readers probably have some idea what it is. So do characters in the world. But about it turns out vampires in the world are quite different to what a common reader might know. And this gets first explained about third way in the book.
Things get explained eventually but I just got tired being confused all the time. Do I need to remember this thing I’m told? Do I rely on my prior knowledge or do I get a different explanation later? Do I reread past parts when I get those explanations in case I took things wrong?
I see why people are excited about all the ideas in the book but it’s an extremely hard read. I wonder whether people are attached to it mostly because they had to work hard to get through it.
