In the world of Divergent, society is divided into five factions - Candor, Abnegation, Dauntless, Amity and Erudite. Every year, all sixteen-year-olds must select the faction to which they will devote the rest of their lives. For Beatrice Prior, the decision is between staying with her family and being who she really is. Her choice shocks everyone, including herself. During the initiation that follows, Tris and her fellow initiates undergo extreme physical tests of endurance and intense psychological simulations, with devastating consequences. As initiation transforms them, Tris must determine who her friends really are - and whether she can trust the man who both threatens and protects her. Because Tris has a deadly secret. And as growing conflict threatens to unravel their seemingly perfect society, this secret might save those she loves...or it might destroy her.
