Gnomon by Nick Harkaway has a plot that is intricate and highly metaphorical. Read it for the intellectual plot.

Examples: have you read any Jorge Luis Borges or Italo Calvino?

M. John Harrison deconstructs plot. If you try to read him just for the plot, you will be bored or baffled.

So if we are talking scifi, is it comparable to dhalgren?

I suppose you could compare M. John Harrison's work to Dhalgren in terms of plot / absence of. But not subject matter or prose style.

Disclosure, I Did Not Finish Dhalgren: The prose style and subject matter did nothing for me. I have never DNF a M. John Harrison book.
