Neuromancer, by William Gibson

Written way back in 1984, Gibson dreamed up and wrote about several high tech things years before they ever came about in reality, such as the internet. In this postmoderm, cyberpunk classic he is responsible for coining the phrase cyberspace, among several others, again way before their inception. The story is a bizarre, twisted tale that is most difficult to follow (or even understand) beyond what is happening on the surface, yet one just while reading there is much to ponder underneath the storied words. Well worth reading, even if you don't wish to delve into the deeper realm beneath the story. Definately a Sci Fi classic written decades before it's time.
