As defined by Waggish: "books that fall into the category of my having empirically observed them being read by a multitude of engineers with a literary bent." No conclusions drawn, but I think it's an interesting exercise.
The list of authors includes some of my favourites: Umberto Eco, Italo Calvino, Milorad Pavic, Neal Stephenson. Also, Borges, Perec, DeLillo. (Maybe I'm an engineer at heart after all.)
Not surprisingly, there is some overlap with Alex Kasman's list of mathematical fiction, though I like the Waggish ambition to focus on "literary" fiction.
No women writers are noted. I think AS Byatt might appeal to left-brained readers, but I can't say I've ever seen an engineer reading her books.
