For me, The Unbearable Lightness of Being-Milan Kundera; On Earth we are Briefly Gorgeous-Ocean Vuong; Love in the Time of Cholera-Gabriel Garcia Marquez. The most tragic, painful, human suffering can be presented and these writers present it in the most excruciatingly beautiful prose.
On Earth we are Briefly Gorgeous-“A woman stands on the shoulder of a dirt road begging, in a tongue made obsolete by gunfire, to enter the village where her house sits, has sat for decades. It is a human story. Anyone can tell it. Can you tell? Can you tell the rain has grown heavy, its keystrokes peppering the blue shawl black?”
What is the beauty for you?
Anything by Jack London.
However a lot of outstanding prose is like chocolate. I like short amounts but it can distract from the narrative. There needs to be a balance between ‘keep it simple’ and an author ‘trying too hard’.
