This book is definitely going to be for some people, and not for others. For the first third of the book, I was trying to figure out exactly what was going on and getting used to the writing style. It jumps back and forth between Cee and Kasey, where one is in third person POV and the other first person. The writing style differed between each chapter that was written, so it was easy to understand the difference between the characters. A lot of the plot points don't make sense until there is a huge reveal about halfway and towards the end and more starts to make sense.

The entire plot is mysterious and I found myself asking questions the whole time that only start getting answered at the end. People might find that a little hard to get into, as it does have a really slow start. The world building was a little spotty, and I was a bit confused with the current dystopian world they live in. I think that led to even more unintentional confusion. However, I really loved the characters. The amount of depth we experienced from them and their struggles was amazing. Exploring the bond of siblings was a major point of this book. There is romance (kinda) but it doesn't have much to do with the actual plot. 

At the end, there were still questions I had unanswered. But after finishing, I couldn't stop thinking about this book. It is the most unique and different dystopian YA book I've read. If you aren't a big fan of ambiguity, I wouldn't say this is for you. However, I really enjoyed this read and how much it made me think.
