Though Tris is still angry with him, she has Tobias use his connections with Evelyn to break out Caleb. Tris’ brother, Caleb, who betrayed her by leaking her secrets to the now-dead Erudite leader Jeanine Matthews, is in jail awaiting execution. But at the request of Allegiant leaders Cara and Johanna, they decide they must follow this directive. The outside world is a complete mystery to Tris and Tobias. When there are enough Divergents, she says, a group of them must leave the safety of their fenced-in city and help whoever is outside. In the midst of this unrest, an old video made by a woman named Edith Prior resurfaces. Another group, called the Allegiant, believes the faction system should remain intact. Evelyn Johnson, mother of Tris’ boyfriend, Tobias, leads this charge. Uprisings have taken place, with some calling for the cessation of the faction system.

Much about the city has changed since Tris secretly learned she was Divergent and chose to train as a member of the Dauntless faction. Those who are tested and fail to fit squarely into one category are called Divergent, and leaders of each faction consider them a threat to the societal structure. The Dauntless are brave, Candor are honest to a fault, and Amity members uphold the importance of peace. Abnegation members prize selflessness and service, while Erudites believe intelligence is key. Everyone belonged to one of five factions based on his or her gifting and personality. Tris Prior grew up in a city once known as Chicago.
