This book was perfect. The angst, the world building, the two MCs!!! I loved everything about it. I had this book on my TBR for a while but I didn't start it because I was scared it was going to be too dark for my tastes. Instead, it didn't focus too much on the "darkness", it focused on the consequences for the MCs, making the story angsty in the right way. 

I'll also add that I love when authors are competent in what they're writing about. It's difficult to find fantasy/paranormal/thriller romances with a believable political plot. This book was perfect in this regard, I completely believed the world building and the reasons behind the MCs action. On the topic of the author's competence, there's a scene with two side characters, a mathematician/physics and a engineer discussing. And obviously the mathematician was making fun of the engineer for approximating pi and g, which as an engineer myself I found hilarious and it's absolutely a conversation I had in my life. It's a small inconsequential scene, but it explains well the care the author had behind everything.
