An epistolary novel is a literary work that tells its story through a series of documents, such as letters, diary entries, or emails. This format allows readers to experience the characters' thoughts and feelings directly, creating a sense of intimacy and immediacy. Famous examples include Mary Shelley's *Frankenstein* and Alice Walker's *The Color Purple*. The epistolary style can enhance the narrative by providing multiple perspectives and voices, making the story more dynamic. It often reflects the characters' personal experiences and relationships, allowing for deeper emotional engagement. This unique structure has been used in various genres, from romance to historical fiction.
