Divergent relies on the 2011 novel by flower Philip Roth, the primary of a triplet. Shailene Woodley (who was Saint George Clooney's girl in Alexander Payne's The Descendants)plays Tris, the lonely adolescent in a very shuddery, ruined futureworld wherever Chicago could be a fortified city-state, encircled by high walls on the far side that is mere disorder.
