An epistolary novel is a literary work that is presented through a series of documents, such as letters, diary entries, emails, or other forms of correspondence. This format allows readers to experience the thoughts and feelings of characters in a direct and personal way, often providing multiple perspectives on the same events. Famous examples of epistolary novels include Mary Shelley's "Frankenstein" and Alice Walker's "The Color Purple". These novels use the epistolary format to enhance storytelling, create intimacy, and develop character relationships, making the narrative more engaging and relatable for readers.
