Gothic novels are a genre of literature that emerged in the late 18th century, characterized by their dark, mysterious settings and supernatural elements. They often feature haunted castles, gloomy landscapes, and themes of horror and romance. Notable examples include Mary Shelley's "Frankenstein" and Bram Stoker's "Dracula," which explore the complexities of human emotion and the unknown. These novels typically include elements such as isolated protagonists, psychological tension, and moral ambiguity. The genre has influenced various forms of media, including films and television, and continues to captivate audiences with its blend of fear and fascination.
