Divergent / Veronica Roth / 487p

 Set in a future Chicago, Beatrice must decide to be a part of one of five factions within the society.  When tested to see what faction she would work best in, she is told that she is divergent - doesn't exactly fit in anywhere - and that she must keep that a secret to protect herself.  This realization is the beginning of Beatrice questioning how truly perfect her society is.

One more dystopian title to add to the YA list (oh Hunger Games, nothing will be as good as you), there's a lot of hype around this one.  I, for one, was not enamored.  Obviously, I'd recommend it to teens interested in continuing on the dystopian path but I would not list it first. (Matched, in my opinion, had a better story with a more realistic romantic side plot.)
