Divergent Trilogy is a series of young adult science fiction adventure novels by Veronica Roth set in a post-apocalyptic dystopianChicago. The trilogy consists of Divergent (2011), Insurgent (2012) and Allegiant (2013).
The society of the trilogy defines its citizens by their social and personality-related 
affiliation with five different factions, which removes the threat of anyone exercising independent will and threatening the population’s safety. Beatrice Prior, who later changed her name to Tris, an Abnegation-born and Dauntless transfer, must figure out her life as a Divergent, while concealing her true nature, and living with the danger of being killed if it is discovered by the Dauntless leaders.
