Like the last couple of "teen dystopia" series I read, this was inspired by all the hubbub of the movies. The back-story and fulfillment of this series was much better than the Maze Runner books; at least it was kind of plausible. The end was a little disappointing, but somewhat expected.
It was interesting... as soon as a coworker mentioned her general dislikes of "teen dystopias" as "angst-filled" I really started noticing it. But once you get past that (and the sense of empowerment as the "most important people in the universe" it gives teenagers), it was a pretty enjoyable series.
