If you liked Hunger Games try Divergent!

Set in post apocalyptic Chicago, society in and around the city has been segregated into 5 factions. Each faction delivers important structure and resources to the city inhabitants. Beatrice Prior, like all 16 year olds, will need to choose the faction she plans on staying with her entire life based on the results of a grueling virtual test. Usually the test results are clear and make the choice relatively easy, unless you are "divergent"! This revelation, a dark secret that Beatrice is told to never mention to anyone for fear for her and her family's lives, drives her decision to leave her family's faction and join a seemingly opposite one. You will experience heart stopping, risk taking action set in Chicago full of intrigue, romance, betrayal, battles virtual and real - your typical teenage day, right? What faction would you choose?
And, of course it's a trilogy. "Insurgent" is slated for Spring 2012. Veronica Roth, the 22 year old author, wrote this book while a senior at Northwestern! She majored in English. A great choice for northshore readers.
And, the movie rights have been signed, too!
