Divergent - Veronica Roth
In a future Chicago, 16-year-old Beatrice Prior must choose among five predetermined factions to define her identity for the rest of her life, a decision made more difficult when she discovers that she is an anomaly who does not fit into any one group, and that the society she lives in is not perfect after all.
I know that this is a massively popular book and I must be one of the only people left who hasn't read it. I checked it out on goodreads, read a few reviews and I've added it to my wishlist. It sounds like a great read so I will definitely need to get my hands on a copy soon; the kindle one is such a good price I may have to buy it asap!
