Explanation:
"Frankenstein", is a horror and science-fiction novel that was written by author Mary Shelley, and which was published originally in 1818. The format, or style, that is used in this novel is known as epistolary, which means that the story develops itself from a series of letters that are written between characters, narrators, or a combination of those, instead of just simply having a narrator tell the story directly. Epistolaries, are part of a larger style called the Frame Story, and in this novel, these epistolaries happen between two of the characters: Captain Walton and his sister Margaret Walton Saville. In them Walton narrates to his sister the story of Frankestein as he hears it when he first meets him during a trip to the North Pole.
