For me, the "Song of Ice and Fire" series by R. R. Martin is the best thing I have read.
I just hope the TV show doesn't rush the last few books. He has always been painfully slow about releasing his books. So much so I really hope he doesn't go out like Robert Jordan and die before he finishes the series. That being said, you cannot argue with his results. It may take him forever to write his next book but when he does they are perfect.
