“Stand On Zanzibar” by John Brunner won the Hugo Award for Best Science Fiction Novel of 1969.
The story is set in the early 21st century; one of the problems caused by the rapid changes of the times is ‘muckers.’ A mucker is someone who has ‘run amok’ and is out to kill as many people as possible. In the book the preferred weapons were knives and swords.
Brunner based his novel on the works of sociologist Alvin Toffler, who coined the phrase ‘future shock’
