Claire Ryan is 15 and wonders why her parents don't pay her attention, why her teachers never notice her hand up in class and why her classmates never talk to her. All this comes to a head on a day when someone finally does notice her, and it's not a good thing. 
 Nix is 17 and has lived in a plain, white room at the Society ever since he can remember. Even the most sensitive people there have a difficult time noticing him. For years they have trained him as an assassin, the most invincible one in the world. 
 What could happen if Claire and Nix were to meet? 
 I was fascinated by this concept. For me, this would be like a nightmare come to life. Being a nobody in a very social and interactive world. It would have been even worse for this to happen as a teenager. At that age, being noticed is of utmost importance, otherwise they wouldn't tryout for teams and join clubs, and spend hours choosing clothing an grooming. Being visible is every thing. 
 It was difficult to watch Nix as his world fell apart, for him to learn that he had been fed a pack of lies by those adults he was supposed to have trusted for his entire life. With no outside influences, he'd never questioned what he was told, where as Claire went to school and learned to ask questions as does every student. Her view of the world was based on wide experiences. 
 As an adult reading a YA novel, I enjoyed the story and the concept. I wasn't too worried that there was little attention paid to the morality of supporting themselves and procuring supplies. A couple of times, Claire and Nix discussed whether they should be concerned about her no longer being at home, and it was a simplistic approach, but considering their status as 'nobodies', it was probably quite appropriate. There was enough details about both of their childhoods and their upbringing that I felt as though I knew them and could empathize with their situations.
