Divergent By: Veronica Roth
I read this before it became a movie, and became uber popular. Honestly I found it a little boring until Tris and Four started dating, that isn't exactly a spoiler because if you didn't know that you've been living under a rock, just joking :) It begins with Tris who is sixteen taking a test that determines her entire future. In the world of Divergent, the world is split into five factions, and Tris has to make the decision in which one choose, no matter the choice she makes. Her world will change forever.
