Game of Thrones. I haven't finished it but so far it's awesome and I highly recommend it for anyone who enjoys reading within that genre. Peoples were always telling me to read it and finally one day a coworker brought it to work, handed it to me, and said not to give it back until I was done...unfortunately I got transferred so I'm in limbo until I get my own copy but if I had a choice I would not have been able to put it down.
Divergent by Veronica Roth is also a great book. I read that and the second part of the series and can't wait for the third one to come out. I think if you like something like The Hunger Games trilogy then you will definitely enjoy the Divergent trilogy.
