Divergent is another book series turned into films. Penned by Veronica Roth, the book takes place in a post-apocalyptic Chicago where people are divided into five factions based on their personalities and values. The trilogy focuses on the experiences of Tris Prior, who lives in the "brave" faction, where inhabitants undergo a harsh initiation process. Tris, the female protagonist with a whole lot of gumption, has a secret, though. She learns that she's actually a Divergent, someone who will never fit into any of the factions, and could be forced into poverty if anyone finds out about her status.
