Frankenstein is a novel written by the English author Mary Wollstonecraft Shelley about the young science student Victor Frankenstein, who creates a grotesque but sentient creature in an unorthodox scientific experiment. Shelley started writing the story when she was eighteen, and the novel was published when she was twenty. The first edition was published anonymously in London in 1818. Shelley's name appears on the second edition, published in France in 1823. Victor Frankenstein reanimates a dead body, and then his guilt for creating such a thing. When the "Frankenstein monster" realizes how he came to be and is rejected by mankind, he seeks revenge on his creator's family to avenge his own sorrow. Frankenstein is written in the form of a frame story that starts with Captain Robert Walton writing letters to his sister. It takes place at an unspecified time in the 18th Century, as the letters' dates are given as "17-." Frankenstein is infused with elements of the Gothic novel and the Romantic movement, and is also considered to be one of the earliest examples of science fiction.
