In the groundbreaking last installment of the bestselling Divergent trilogy, Tris and Tobias' fates balance on the point of a knife. Evelyn Johnson, Tobias' mother, now rules Chicago along with the rebels, but life is the same as when the factions thrived - possibly worse. Even after Tris risked her life to reveal the truth about the creation of the factions, Evelyn refuses to do anything about it, continuing to lock everyone inside the city at the hands of the rebels. In the midst of riots and confusion, Tris and Tobias join the group of people ready to break out of Chicago called the Allegiant. But they meet several casualties along the way, including immobilization and deaths. And even when the Allegiant cross Chicago's borders, the truth about the world is uglier than they ever imagined. Chicago's factions were simply an experiment by the American government; Divergents are pure-blooded, and everyone else is considered "genetically damaged"; and every single thing the city of Chicago went through was orchestrated, including the Abnegation massacre. From there on, it all begins to deteriorate. Secrets, rumors, and betrayals fly as bonds of love are tested. The Allegiant rises against the all-powerful US government. Friends are imprisoned and die. But in the end, all it takes is one choice. And though Tris is a genetically-pure Divergent, she is far from invincible. A gorgeous, shattered, heartbreaking story, Veronica Roth weaves the last Divergent book with lost kisses and the salt of tears.
