The Novels of Mary Shelley

Mary Shelley wrote seven novels as well as short plays, travelogues, and biographies, widely respected in their time but largely forgotten until feminists worked to rehabilitate her reputation. The site made me include ten, so I included both the 1818 and 1834 texts of Frankenstein, Maurice, which is more of a short story, and the short plays Proserpine and Midas, usually published together. How many have you read?
