I didn't like this as much as Mechanica. I was frustrated by how predictable the Ashes plot point was, when it had been made up to be a big open question/plot point. But it's so easy to predict halfway through Mechanica that having a reveal in the sequel felt very underwhelming. And also reinforced how dense the main character is. 

The writing was sometimes a bit repetitive - we hear a lot about how unique Nicolette, Caro, and Fin's trio relationship is. 

I enjoyed the additional world-building here in Faerie (and on the journey to Faerie).
