This was beautiful. I always wonder at Leigh Bardugo’s ability to wrap up an ending in what seems like a short span of pages. I don’t want to spoil anything so there’s not much I can say, but this is probably my favorite after the first Six of Crows book. You can clearly see how her writing has improved over the course of writing the Grishaverse. 
I liked how it revisited and reviewed themes and characters from the previous books, as well as building on the complex magical world that they live in. I feel like there’s still room for sequels, and I await them with great anticipation. I also feel a bit of sadness at finishing such a wonderful collection of books that has made me think and feel so much, and has also brought me together with people in real life. I’ll read the anthologies, and reread these books, but there will never be anything like reading this again for the first time.
