An exciting, well-written page-turner along the lines of Divergent and Hunger Games. The world building is great (the U.S. is split into warring east/west halves), and an interesting and fairly complicated situation is set up by the end to make you want the sequel immediately. 
 Is the story line of teens realizing they're being lied to by the establishment getting old? Maybe a little, but I think teens enjoy the idea of being the ones to figure out truths and possibly save the day. 
 An easy recommendation for middle and high-schoolers who like adventure and dystopias. There's some violence, and there may be a little too much romance for some readers.
