Divergent ~ Veronica Roth. This 'dystopian society is divided into five factions, each dedicated to the cultivation of a particular virtue--Candor (the honest), Abnegation (the selfless), Dauntless (the brave), Amity (the peaceful), and Erudite (the intelligent). On an appointed day of every year, all sixteen-year-olds must select the faction to which they will devote the rest of their lives.'
