William Gibson is the only writer whose books I will buy without knowing what they're about, without having read reviews. So far, all of them have been great. He also writes his books in 'trilogies': three books that, while they often have different main characters, share a setting and with cameos of repeat characters. And interestingly, his settings have become less and less futuristic: Zero History features only tech that exists today. And yet Gibson manages to write an excellent cyberpunk novel.
Because to me, cyberpunk is about dealing with/in information, and Zero History (and its predecessors, "Pattern Recognition" and "Spook Country") is exactly about that, packaged in an amusing decor of fashionable hotels.
I think it would make an excellent setting for an RPG -- using the Over the Edge mechanics.
I'm looking forward to Gibson's next book -- I wonder what he will come up next.
