"Novellas provide a uniquely special kind of reading experience, and require their own kind of skill to craft. Shorter than a novel, but still often expected to carry the same narrative heft, and longer than a short story, novellas are exciting in their uniqueness. They can be re-read more easily and therefore provide more thematic satisfaction for the reader.
As for defining a novella, that depends on who you ask. Typically, a novella is any piece of fiction that's shorter than 200 pages (though some argue for 150 pages), but not so brief as to be considered a short story. Here, we're going off general consensus.
These are your must-read novellas, separated neatly into different styles and genres. Here, you'll find a hefty selection of classics, as well as many modern novellas separated out by genre. And so many of these masterful short books come from all around the world."
