Star Maker
A man walks out of his suburban house after a quarrel and is swept off the hillside into a tour of the entire history of the cosmos: minds, species, galaxies, and at last the maker of stars itself. Written as fascism gathered in Europe, it is less a novel than a telescope aimed at everything. Borges admired it; Arthur C. Clarke called it one of the finest works of science fiction ever written.
There are no characters, no dialogue to speak of, and no plot beyond ascent. It is a guided tour with a narrator who apologizes for skipping galaxies. The prose can go gray for pages, the invented species blur together near the middle, and the climactic vision asks you to accept a cosmology on faith. Readers who need a person to follow will find one paragraph of marriage at either end and two billion years of abstraction between.
The case for it and the rest of the canon open with Pro.
