It was hard for me to rate this book because I loved certain aspects of it...and then did not care for the rest of them. So I settled on 3.5 stars (for now) and we'll go from here!

Before I say anything about this book, there is one thing that's been bothering me; not about the book per se but about some reactions to it. Mainly: the comparisons to Six of Crows.
Where exactly do people see that?
Sure, the book has a heist in it. The found family trope (notice the word "trope") plays a role to some degree. They're not exactly doing things by the law. And by now I've run out of similarities and gone straight back to "why are you constantly comparing these two books". 
Listen, I understand if you advertise this book as "if you've liked SoC you might want to check out this one!" but that is the only time you should even be thinking about any kinds of comparisons in my opinion. These books share a very, very popular trope in (YA) fiction, and criminal underground activities. That is it.

Alright! Back to the book and what I liked and didn't like.

What I liked:

I was a fan of most of the characters! Tho their introduction was a bit short sometimes, they grew on me almost instantly. They had a fun little dysfunctional found family situation going on, there were understandable tensions and heartfelt friendships (and more). What I found beautiful was also how the author navigated the world of her book and how each character faced their marginalization (if present; not all of them had even more challenges heaped upon them by the outside world like that) in their own, unique way. The fact that magical objects had been stolen by European families rather than stay with their original cultures as well....we all know what this is about lol

The first half of the book, right up until the heist, was beautiful. I was warming up to everyone, things were fun but tense, I had no idea where we were headed and I was in for the ride. But then....

What I didn't like:

...then came the second half of the book (more or less; I don't remember the exact page numbers). Sadly, this was where the book lost me. I don't know if it was because I read it too fast (sometimes it happens, though rarely), if I just expected something completely different and was thus thrown off the game....I'm not sure. The latter half of the book feels incredibly rushed to me, with completely different objectives being woven into the narrative, with twists I didn't even see coming anywhere (and not in an entirely good way - I'm of the opinion that foreshadowed twists you can sense in the narrative but not fully realize until it's too late are the most beautiful thing an author can manage to do). And I just wasn't a big fan of it. Maybe it was also the seemingly random ways the characters came to conclusions (or was I too stupid to follow them? We will also never know)? I'm not sure. Anyway, I didn't like it and it sadly knocked my rating down a few notches.

Overall opinion: I enjoyed myself up until the later half which I just read through with increasing confusion. Emotional things left me pretty cold in the end, which is another sign for me that I didn't really enjoy myself.  I might pick later books in the series up to see if anything changes/if my own opinion changes again, but so far, we will leave it at: 
First half: 4 Stars
Second half: 2 Stars
