Definitely recommend this duology! The skill in writing went up tremendously between this book and the last. While there were still some things I would change, it did not stand out to me the way it did in Grim Lovelies. The only issue I had with this book was the crux was too easy to figure out. I knew it from the beginning and just wanted to scream it into the book the whole time. Other than that, the reading was very enjoyable. I LOVED the magic system, it was very unique and well thought out and executed. Overall, pick this up and you are sure to have a pleasant experience!
