From Goodreads:

In Dhalgren, perhaps one of the most profound and bestselling science fiction novels of all time, Samuel R. Delany has produced a novel "to stand with the best American fiction of the 1970s" (Jonathan Lethem).

Bellona is a city at the dead center of the United States. Something has happened there…. The population has fled. Madmen and criminals wander the streets. Strange portents appear in the cloud-covered sky. And into this disaster zone comes a young man–poet, lover, and adventurer–known only as the Kid. Tackling questions of race, gender, and sexuality, Dhalgren is a literary marvel and groundbreaking work of American magical realism.

From Goodreads:

Six days ago, astronaut Mark Watney became one of the first people to walk on Mars. Now, he's sure he'll be the first person to die there. After a dust storm nearly kills him & forces his crew to evacuate while thinking him dead, Mark finds himself stranded & completely alone with no way to even signal Earth that he’s alive—& even if he could get word out, his supplies would be gone long before a rescue could arrive. Chances are, though, he won't have time to starve to death. The damaged machinery, unforgiving environment or plain-old "human error" are much more likely to kill him first. But Mark isn't ready to give up yet. Drawing on his ingenuity, his engineering skills—& a relentless, dogged refusal to quit—he steadfastly confronts one seemingly insurmountable obstacle after the next. Will his resourcefulness be enough to overcome the impossible odds against him?

I think, though it's only a guess, that the more "poetical" parts are from a certain notebook.
