I try not to be a cover snob, but I have to admit I put off reading this book because of the cover. However, I am so glad I did read it because it was amazing. At first I found Em's initial naivety a bit unbelievable and annoying but I changed my mind as I watched her character progress through the story. I did think she should have wised up sooner for such a smart character though. I absolutely loved Chase. His strength and love for Em were the standout features of the story for me. I also loved that he had made mistakes because it gave him so many facets. In general, I think the book was definitely a character driven novel with really believable motivations and responses. Including how different people react to similar or the same situations. 
 If you like Dystopian novels I definitely recommend giving this one a go and ignoring the boring cover.
