Haven't heard the term "abstract" applied to a plot, unless you mean highly metaphorical? Genuinely curious in case it's something I'd like. What's an example, without giving too much away?
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.
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.
