Daughter of pioneer feminist Mary Wollstonecraft and radical philosopher William Godwin, lover and wife of Percy Bysshe Shelley, author of Frankenstein and creator of the science fiction genre, Mary Shelley has remained a figure both undervalued and enigmatic. In this authoritative, ground-breaking biography, she is finally restored to her rightful stature as one of the major figures in English literary history.

Here for the first time is a full account of Mary Shelley's career, significant areas of which have never before been examined: her precocious childhood, her adolescent liaison with the radical poet Shelley, her creation of Frankenstein at the age of nineteen, her tempestuous but brilliant married years with Shelley, and, of particular note, the dramatic second half of her life, after Shelley's death. Emily Sunstein has also discovered previously unknown works written by Mary Shelley and traces the development of her unjustly clouded posthumous reputation.
