I'm currently reading the classic The Count of Monte Cristo. I't's pretty good so far - kind of slow at the moment. He's working his way back into the high-class society to wreak havoc on those responsible for his imprisonment. I've been on a classic run reading Catcher in the Rye, A Brave New World, and 1984.
The entire Game of Thrones series is fantastic. As well as the LOTR and Ender's Game series.
The Kite Runner and A Thousand Splendid Suns by Khaled Hosseini were excellent reads.
If you're interested in thriller/mystery, anything by James Patterson, Michael Connolly, Patricia Cornwell, Tess Gerritsen, or John Grisham.
My next read is Snow Falling on Cedars by David Guterson. It was highly recommended by a friend of mine.
