In this dystopian Chicago, citizens are divided amongst five factions, each of which is focused on one personality trait--honesty, selflessness, bravery, peacefulness, intelligence. When children hit the age of 16, they publicly declare which faction they will live in. Many stay where they were raised, but Tris and her brother choose otherwise--she selects Dauntless (the brave), while he leaves for Erudite (the intelligent). 
 When Tris arrives in Dauntless, she's in for a surprise--she may have chosen them, but they have to choose her. The initiates go through a grueling set of emotional and physical trials, and only ten of them will be accepted. The rest will become factionless, which is a fate worse than death. 
 At first, this read a little too much like the Hunger Games for me. Major city separated into sections, characters literally fighting one another for survival. And everyone's intimidated by the girl, and there's a little romance going on beside the scenes... yep, read this before. 
 But I really got into it closer to the end, when the controversy kicked in. And of course there's controversy, because this will be a trilogy. Factions disagree with one another, there's some big, secret plot brewing, that Tris is unknowingly a part of. 
 I'm expecting big things for book two... which isn't coming out until May. My impatience is kicking in.
