Mary Shelley has only recently emerged from the shadows of her famous parents, Mary Wollstonecraft and William Godwin, and that of her husband, Percy Bysshe Shelley. Today, Frankenstein (1818, 1831) is one of the most popular classroom texts in high school and college, and Mary Shelley's other works are attracting renewed attention. This reference is a comprehensive guide to her life and career. Included are hundreds of alphabetically arranged entries about her works, friends, relatives, residences, fictional characters, allusions, and more. Some entries briefly identify and contextualize their topics, while others offer more extensive discussions. Many entries cite sources of further information, and the volume closes with a bibliography. The work is fully cross-referenced and includes a detailed index and an appendix that discusses the sources of Shelley's quotations.
