I was dying to read this book and it was one my most anticipated reads of 2016. 
 Cecelia Ahern is pure genius for creating an unbelievable world and a nonpolitical system that motivates its citizens actions. My mouth literally hung open with disbelief at the way these people lived their lives and how they treated others. It was damn awesome and sad all at the same time. 
 I won't go into detail about the world because it is so much better to learn about it as you go. But I will say that the society came up with the Flawed system to get rid of the greed for power and money that consumed the world in the past, as a way to make sure that never happened they decided to punish people who committed acts against society by branding with like pigs with a red F for Flawed on different parts of their body. It can be their tongue, temple, hand, sole of the foot, or chest so that others can see their crimes(sorta like a scarlet letter) and are shunned by society, those who see themselves as "perfect."But with the nature of some, people want power regardless and Celestine gets swept up in the middle of it when she helps a Flawed man, something you are not supposed to do. This sparks a rebellion long in the making. 
 I liked the story a lot. I feel that this series has a lot of potential to be great. I will say that I felt that there wasn't enough of the story being told because I was left with lots of questions and felt that the Judge Crevan should have played a bigger role in the middle. I also was disappointed we don't get to see more of Carrick, I was definitely looking forward to that. The book also ends so abruptly that I was just confused. There was inkling that more was to come or what we could expect next for Celestine. But being as this is the first book, I am still excited to see what happens next.
