First thing about this book...the dual POV drove me insane!! But in a good way. There were two times in the story, when a chapter would end and the POV shift would happened, that I skipped over the in-between chapter because I couldn't handle leaving Elias or Laia's situation open ended. I had to know what was going to happen next. 
 I found myself more drawn to Elias' story then Laia's, but I still enjoyed both of them. What I loved about this story is that usually I can see where YA stories are going before they get there, but with this one, it was one crazy turn after another. It was so refreshing. 
 I also found this story a little darker then I thought it would be, but in a necessary way that added to the authenticity of the story and world. Definitely a book adults would enjoy as well as YAs. Also, the audiobook narrators are great.
