One of the books I read in my formative years. It contains a real message about extremism and the ability of people to resist whilst working within a system. Themes of rebellion and addiction are explored too.
If is predictive sci-fi you are after then this book contains the first mention I have seen of wall size television screens. Something that is entirely possible today and we are moving towards the totally immersive experience as well. Avatar 3d and similar films are showing the way visually and the tactile technology isn’t far behind.
If you haven’t read this book then you should. It is a really good commentary on the state of society. Places exist that are still like this book, they shouldn’t but they do.
