Set in a utopian world of a destroyed Chicago, we are never told if the rest of the world survived the cataclysmic event that destroyed the city, but we can assume it was war as to stop all wars and human conflict society is divided into factions, and as you come of age, at 16, you must choose the faction you'll be for the rest of your life, and the faction you choose determines where you live work and you you associate with. It would be interesting to find out what happened to the rest of the world, as we are only seeing what life in one city in the U.S is like. The factions remind me of high-school clicks, jocks, nerds, stoners, narks, losers. But according to the narrator, Tris, there hadn't been a murder in the city for a long time, so it's working for them.
Yes, it was better then the Hunger games. But I wanted to know about the rest of the world.
