It is such a shame that I could not give this book a higher rating, as I found the ideology behind the conception of the story, as well as how the book was physically set out, to be both unique and interesting. 
 This story is told from the split perspective of Lyra and Gemma. Gemma is your average teenager, obsessed with how her peers perceive her and concerned over high-school dramas. Lyra isn't actually a human being at all, and is instead a cloned replica of an original person. She lives, along with the other replicas, on Haven Island. There she is subjected to testing and harsh living environments. 
 Gemma and Lyra's stories combine about a third of the way through their individual narratives. From this point, my adoration with the story quickly dwindled. What was originally an exciting concept, to lay the book out in two split sections, became a dull one. There were subtle differences in the plot that made each worth reading, but often the scenes overlapped and it just felt like you were reading the same thing twice over. 
 The focus of this book was on identity and it was interesting, at first, to note the subtle different ways two people could react to and what they could take from the same happenings. I appreciated what the book was trying to do, but, after a while, this felt dull and repetitive rather than exciting and innovative. 
 Also, if this book had continued to focus on the two original characters, it would still have managed to hold my interest. Instead, there were characters brought in, purely for added romantic drama, and this ruined any remaining affinity I had with the book. There were so many unnecessary characters and surplus drama when all I cared about was the central plot and the internal struggles of the protagonists. The extras felt like just that... extra. And not the good kind. For me, they served no purpose and I would have greatly preferred if this book had remained focused on the original and central topic of the concerns over identity, as well as the dystopian society being created, and continued to explore and open these themes up. 
 In all, I found this an inspired concept, but unfortunately, it was just not for me.
