It's very Tolkien-influenced. I can see the amount of mythcrafting that must have gone into it, but the writing style is tough to get invested in.
Skip this part if you don't want to hear an old man complain:
You kids today have no idea how great you have it. When I was 14, there were no kids or teen fantasy books, there wasn't even a teen section in the library. If you wanted to read fantasy, this is what you got. I look back at series I loved in high school, like Thomas Covenant, and I wonder how the hell I put up with that writing style. But they were all like that. It's like they hadn't learned that you don't have to write like Tolkien to create worlds like he did.
Basically, this just isn't how fantasy books are written any more. It might be a really great story, but it feels outdated because of the language used.
