The main character, Beatrice, is part of a faction that thinks of others rather than themselves. When the kids turn 16, they get to choose a faction. Beatrice chooses a faction that is opposite of her faction at the time. They all go through training, but several kids drop out by the end of it. At the end of the training, the other factions that oppose Beatrice's old faction go into a war. This book is a good read; it goes by fast, and the story is just outstanding. The story is good for everyone. You would like this book if you like… The Hunger Games, The Giver, and dystopian books.
