Divergent by Veronica Roth is a book reccommended to my by my 13 year old son, who got it from one of his friends.  This distopian novel, set in Chicago in the not so distant future, had me hooked.  This was a book I could not put down!  I stayed up until 2:00am just to finish it!  The characters, the setting, it could so happen to us!  Highly reccommended for those who liked the Hunger Games or The Maze Runner trilogies.  You don't have to wait for the sequel...it has just been released and is called INSURGENT!  Yet more choices for Tris and Four.
