I have been reading A Game of Thrones this year, but I subbed in an English class for three days last week and decided to read the book that they were working on: Ender's Game by Orson Scott Card. It was on my "list" to get to someday. Made a nice excuse to borrow the teacher's copy and be able to help the kids with the study questions. Really enjoyed it. For a sci fi book written in 1977, I found it pretty current. Most notable for me was the treatment of the human, the layers of emotions and motives and power, internal structures, and the search for identity and role separate from manipulation.
Page 102: "Listen, Ender, commanders have just as much authority as you let them have. The more you obey them, the more power they have over you." (Dink)
Page 231: Perhaps it's impossible to wear an identity without becoming what you pretend to be.
Page 241: "...If you try and lose then it isn't your fault. But if you don't try and we lose, then it's all your fault." (Valentine)
Definitely recommend it.
