Divergent by Veronica Roth
Five factions one time to choose which one you want to be.
"Fear doesn't shut you down, it wakes you up"
Based on the future in Chicago
There are five factions, Dauntlass, Amity, Abnegation, Candor, and Erudite. When you are 16 you take a simulation test and they give you which one you acted like under the simulation. You then pick a faction you can change factions or not. Then you got to your new faction if you don't like it or leave it you go to the factionless. Divergent is where you act like more than one faction while you are under the simulation.
