If you like this genre (or are feeling nostalgic) also check out William Gibson's Neuromancer. It basically started the whole "cyberpunk" genre:

Drug addict code cowboys living in Japan, hired to retrieve the consciousness ROM of another code-cowboy, working for a reclusive mega-wealthy family - who exist offworld in a Las Vegas style colony - and using their secret AI entity to navigate cyberspace in order to get the ROM.

NOTE: Like Stephenson coined "metaverse", Gibson termed "the matrix".
