In the past few days I've had several people ask me for more books like Divergent  by Veronica Roth. If you haven't read Divergent yet, it takes place in a future in which all members of society are divided into five factions. When it comes time to choose her future, Beatrice learns that she is Divergent, not fitting into any of the five groups. She also learns that someone in the government is hunting down Divergents and killing them. It's full of action and adventure and it's great!
