David Lightman is just an average teenager. Except that David has only one interest in life...the world he escapes to through his home computer. By dialing the telephone and inserting a program into his machine, Divid "hitch-hikes" through the universe, traveling on vast communications networks and "talking" to people like himself. Along the way, he also taps into huge computer banks and changes data-like his high school grades.
