From the back cover: Laura Webster's on the fast track to success. A bright young star in a multinational conglomerate, she's living well in a post-millennial age of peace, prosperity, and profit. In an age of advanced technology, information is the world's most precious commodity. Information is power. Data is locked in computers and carefully rationed through a global communications network. Full access is a privilege held by few. Now, Laura Webster is about to be plunged into a netherworld of black-market data pirates, new-age mercenaries, high-tech voodoo... and murder.
See also "Islands in the Net" by Bruce Sterling (IMNHO).
Ed: BTW, for a newer book (2017) that plays with some interesting concepts - see "Gnomon" by Nick Harkaway. Just don't read a summary or too much about before you start - much of the pleasure I found in it was trying to "figure out" the book as I read it...
I'd recommend for example (in no particular order - just some great books imnho):
Earthsea quartet by LeGuin
Dune by Herbert
South of the Border by Murakami
Islands in the Net by Sterling
Foundation trilogy by Asimov
Speed of Dark, by Moon
Accelerando, by Stross
Murderbot diaries, by Wells
A Fire Upon the Deep, by Vinge (and Rainbow's End by same)
2312, by Robinson
And many more, I'm sure :)
There's a much smaller co-op at the heart of 'Shockwave Rider' by John Brunner, but discussion of the mechanics is central to the story. This is an incredible book.
T.R.Napper is also worth looking out for. "Neon Leviathan" is not what i would call a masterpiece, but the author seems promising.
