If you are looking for some good SF read I can't recommend "Dune" enough, this thing is a masterpiece.
As far as right now goes, I just started "The girl with the Dragon Tattoo", too early to give an opinion.
Dune is great, but don't stop there. Read the rest of the series (I don't care for any of his Son's books though, so not going to recommend those, but there are those that like em).
