The pacing was off, which made it hard to feel invested in the mystery. Every clue resulted in a different murder, and the FMC was present for all but one of these. There was not enough build-up of who it could be as red herrings. It felt more like ??? and then the reveal. 

The first half of the book involved a lot of magic system and world-building (Trinkets, Court system, Mystics, and Unbounds), which made the main mystery feel slow. Everything happens in the last 40 pages, and it feels very fast compared to the rest of the storytelling. 

There was also a LOT of fashion interjected into the story, with detailing everyone's outfits/brand dropping and the

enchanted hedgehog that picks her outfits

that I thought would have more impact on the plot besides brief interactions between the FMC and MMC.

 I want more of Dovey and Grant since

they did not even kiss or express any emotions for each other (besides flirting), but yet she took great risks to protect him and disregard Elric for the first time in 200 years

I would read the sequel since I liked the FMC and MMC and the magic system/world are interesting!
