Beatrice Prior is on the brink of a decision everyone in the world must make: five factions, five possible futures, five lives. She has a plan: she’ll make the bravest choice and leave Abnegation to join Dauntless, even though it means leaving her family behind.
But when tragedy strikes at the Choosing Ceremony, everything changes—her world, her plans, even Beatrice herself. Her decision will lead her to the heart of a secret revolution, where a boy with secrets as dangerous as her own—a boy known by a number—may be the only person she can trust. Because sometimes, the path you choose doesn’t just change your future. It changes the world.
