This book really drew me in. Great pacing. Strong, resourceful female heroine - much more interesting than the pathetic helplessness of other female main characters in some YA books. No character seemed to be armed with too thick a plot shield, and I was always on my toes waiting for the demise of someone I liked. 
 I would have liked to see more development of how this post-apocalyptic society came to be: more history, more inter-district political wheeling, and so forth. But overall, very good in its category.
