I'm not really sure how I felt about this book. I put it down for years, and restarted it 2 or 3 times. I struggled with the format, the sub-chapters were confusing at times, and it was hard to follow. The ending was strange and anti-climatic. 
 I think the biggest problem is that much like Gone Girl (which it was compared to in some of the reviews) I just didn't really care about any of the characters, so I didn't care what happened.
