In this duology opener that reimagines the world of Divergent, Beatrice "Tris" Prior's plan to leave Abnegation for Dauntless is derailed when factionless rebels interrupt her Choosing Ceremony, resulting in the death of her friend. During the chaos, Tris spots Evelyn—the supposedly dead wife of Abnegation leader Marcus Eaton—alive, armed, and dressed as an Amity woman. After her brother Caleb chooses Erudite, Tris stays in Abnegation, but is forced to flee when her father attempts to erase her memories. With her mother's help, Tris escapes to the factionless underground, where she meets Four, a Dauntless boy with dangerous secrets who is known only by a number. As she befriends other "faction failures" and navigates the rebellion, Tris realizes that no faction is what it seems, power is deeply corrupting, and the rebels may be justified in wanting to destroy the faction system.
