I wavered back and forth whether to give this book a 4 or 5 star rating. My first instinct was to slap a 5 on it and be done. Collins wrote a great, thought-provoking book. Internally, I felt like any part of me that would want to give this a 4 would be based on personal feelings or bias about things that didn't turn out the way that I wanted. 
 After sleeping on it for a night, I realized that the book really was a 4 for me, biases aside. There were a few inconsistencies that didn't ring true with the other two books, which shaved a bit off the rating for me. Even with that, I still find myself thinking about the book a full day later. This story was the darkest of the three, but Collins did a great job of letting the story unfold in a natural order. She was nice enough to give us some closure and a partial happy ending, but didn't sugarcoat anything to please the readers. Kudos to her for sticking to her integrity, even at the risk of offending some fans.
