A novella is a written work that is longer than a short story but shorter than a full-length novel. Typically, it ranges from about 20,000 to 40,000 words. Novellas often focus on a single theme or character, allowing for a more in-depth exploration of ideas than a short story while remaining concise compared to a novel. This literary form has been popular among various authors, including Franz Kafka and Henry James, who have used it to convey complex narratives in a compact format. Novellas can be published independently or as part of a collection, making them accessible to readers looking for a quick yet engaging read.
