The language. It's lush, heavy, and winding. Some will hate it, some will love it. There are things that could be streamlined. It's maybe a bit Dickensian to me, and suites the court setting of highborn nobles. Granted, sometimes there are sentences that repeat the same idea twice or as an echo a little later but I can forgive that as the plot moves along with a good pace and doesn't go stale because of the extra flourishes. The language is complex, sentences can go on long but to me, it fits the surroundings and the main character. The writing gets lighter in the second half as there is more dialogue. I appreciate how different the speech between the court and the Heights is.
This is a story that starts in a court in a society that is confined and oppressive. Dangerous for anyone who should step out of their place. The author drops names of other cities, countries, families, and expensive items which gives an air of a palace of true comfort and luxury but also one where status matters more than anything else.
The main character, Inna, is wonderfully morally gray. She does nice things and very questionable things. She is clever and can muster up confidence befitting any highborn lady but that doesn't always serve her well. She fights to keep herself free and to decide her destiny herself but it doesn't always go her way.
I enjoyed all of the story and the setting. I feel like the story could have benefitted from a little more length. That way the story would have had more time to breathe and the sorrows would have become really poignant. I would have liked to see a little bit of Inna's life and thoughts in the court before the rapid changes. Still, I read the story within a few days of starting as I found the main character and the world interesting. Considering that meant almost missing a work deadline, one would be fair to say I really liked it.
Word to the wise though, this isn't a book everyone is going to dig. If you like a light book with tons of magic and fantastical things and creatures that is written to give a few hours of distraction and evoke mostly positive feelings with no true threat to the characters, then turn away. This is definitely fantasy and full of court schemes, but it's low key (only the presence and influence of a few spirits), character-driven, and has many sorrowful, even tragic, elements. But I'd definitely recommend it and will go on to read other books by the author.
