Amazon Description:
During the highly competitive initiation that follows, Beatrice renames herself Tris and struggles to determine who her friends really are—and where, exactly, a romance with a sometimes fascinating, sometimes infuriating boy fits into the life she's chosen. But Tris also has a secret, one she's kept hidden from everyone because she's been warned it can mean death. And as she discovers a growing conflict that threatens to unravel her seemingly perfect society, she also learns that her secret might help her save those she loves… or it might destroy her.
