A novella is a written work that is longer than a short story but shorter than a full-length novel, typically ranging from 20,000 to 40,000 words. It allows authors to explore complex themes and characters in a more concise format, making it a popular choice for both writers and readers who appreciate brevity without sacrificing depth. Novellas often focus on a single incident or character, providing a snapshot of a larger narrative. They can be standalone works or part of a collection, and many famous authors, such as Franz Kafka and Henry James, have contributed to this genre, showcasing its versatility and appeal.
