House of Earth and Blood

Sarah. You can not use existing words and give them a new meaning just because it happens to suit you. You have quite a lot of influence among young fantasy readers, and I fear that I will be hearing a lot of people talking about Vanir as if it was a synonym to sidhe, and other words you have used. It seems to me that you didn't even bother checking if the words already existed and had a meaning.

And the names... sigh

And the complete mess of mythologies and cultures and... eh.

I would love to like Sarah J. Maas, but I don't.
