Query: The future of cyberspace

The MarginI'm not into computers, too old. I can search the web, use word processing and send email, that's about it. But this book captured my attention and got me to thinking--what if?I don't know why it doesn't have a higher rating on Amazon. Digital Fortress has all the makings of good thriller, with intrigue, mystery and some computer enlightenment thrown in.Marvin Wiebener, Author of The Margin
