/lit/ - Literature

/lit/, I’m searching for a forgotten or at least very overlooked writer I read about many moons ago, but only remember few specific details about:
-born 1st half 20th century
-active largely in the 2nd half and perhaps very early 2000s
-published two novels, of which the second one was a minor success
-didn’t publish much else
-his work was most likely classified as post modern fiction
-language was most likely english or perhaps some other west european language, but definitely not german (my mother tongue)
-I think he might have been american?

I hope that the details are not too vague for you

Is John Brunner any good?
I remember hearing very good things about him.
