Firstly I have to say that I loved the cover for this one, and the premise was intriguing. There were a few places however, where the execution failed. I think the primary issue was there were aspects of the worldbuilding and character backstories, that gave the impression that there should have been an earlier book or more development, which was a little jarring and left me feeling a little lost at place.
That said it was an enjoyable enough read, and the plot and writing flowed well, and I did enjoy the characters. There were some darker themes, and while the main protagonist is a teen, this book could not and should not be pushed into the YA section.
