John Brunner (1934-1995) began working as an author by turning out some well-written, but not very original space operas. By the late 1960’s he had begun experimenting with novel structures. Many of his novels written in the 1970’s are almost prescient, hitting on the idea of computer viruses, and environmental concerns bordering on catastrophes. In the 1980’s, he attempted to return to the more mainstream books of his early days, with dwindling success.
I prefer his early space operas to his more popular experimental novels and haven’t attempted any of his late ‘mainstream’ work.
