I'll be short and simple. 
 I agree with a lot of other people. 
 WRITING STYLE: really good 
 SUSPENSE LEVEL: over the top (kept me up 'til 1:00 am) 
 CHARACTERS: not developed well enough. Not necessarily "one dimensional," just not given enough time to connect to them. 
 PLOT: unoriginal. It was The Selection, Hunger Games, and X-Men rolled into one. And there was even a scene from Star Wars in it. 
 (view spoiler)[ Also, the ending was not satisfying. It felt like the ending of the Divergent movie. You know, where they're all hurt and sad and riding a train off into the sunset. (hide spoiler)] I definitely don't feel like reading another two or more books to find out what happened. 
 So yes, I enjoyed it, but was also frustrated by it.
