This book was really amazing and my only regret is that I didn't try to read it all in one sitting. It's pretty dark, which is probably why it held my attention and had me wanting to read more. I still can't really wrap my mind around what happened and I definitely had to look up what others have said about the book, because the ending had me confused. After reading other reviewer's interpretation of the ending, I was able to understand it better but I definitely need to reread the book again. 
 I believe this book deserves a higher rating on Goodreads. The writing is phenomenal and the plot and concept is as well. Just because it may make you think a little bit about what the ending means shouldn't be a reason for someone to give this book a low rating. 
 You need to read this book. What are you waiting for?
