Celestine North is a lucky girl, with a happy family and a loving boyfriend. Everything is almost pretty and golden. But her society isn't and so will be the decision Celestine makes in the book. 
 It's when Celestine starts to live on the rejected side of the society that thing gets hard for her and her view of the world began to shifts. I read not so many happy reviews about Flawed but I've a different opinion, but I really enjoyed the travel, both of thoughts and moral that Celestine makes and how she began to fight for something more, for something better. 
 The point is that: I felt her. I felt emotions, I cheered for her, I watched over her, I've been proud and happy and I cried. That's why this book won over me, even with its flaws too. 
 Like, really I didn't like how Ahern has been super vague about really important details. 
 Since Flawed is set in dystopic society, I think that it's extremely important to know how and why the state of Humming was formed. And how really the Flawed system can work without killing of economy and working... since people can be also punished for bad jobs' moves. 
 Also I wasn't really convinced by the sudden changes of opinions that many side characters have during the story. Celestine makes more friends and allies than enemies, and I think that it's kinda strange in a world where Flawed people are treated like less human beings. At the same time I feel the message that Ahern sends ( or at least I think she does). And it's truthful: people don't care about bad things until they're touched by it. 
 Talking more about the characters, and returning to Celestine, I loved how she grow up and at the same time she remains a young girl, with her problems and way to act. She becomes a better person. She looked real to me, with flaws and everything. 
 Also, the so much feared love triangle... I didn't see it all? Art was kinda hateful, really full of himself and concerned only for himself. At the same time I didn't think that Carrick, another Flawed that will be part of the heroine's journey, was such a good love interest because during this first book I couldn't see any sparkle of love between him and Celestine. 
 What I saw was a normal human bond formed during a period of stress, life and death situation. Anyway, Flawed impacted deeply on my feelings with the concept of what is human and what the society, created by humans themself, try to dictate some kind of pure ideal of human being.
