It's possible I'm biased, but anything Leigh Bardugo writes is an insta-buy for me, and this was no different.
It started a little slow, it took a little bit for me to get to know who Luzia was. I will say, part of that was absolutely the point though - she has spent so long hiding herself that she also needed to relearn who she was. It was a journey we took together.
Santangel. Maybe I just have a thing for emo sad boys but he had my heart right away.
While it's written in 3rd person, each chapter is from the pov of different characters throughout the story. Personally, I love how that gives us a way to see Luzia as other people see her - and how their view of her changes over the course of the story.
The only thing that was a little tough, was (as this was set in Spain) a lot of Spanish terms were used. I don't think it's a negative by any means, and most of the terms I could parse out just from context clues, but it is something to be be aware of going into it.
