I thought I might make a note here about the title of the Mary Shelley Memoirs book. When it first launched in paperback the title was "Frankenstein Diaries: The Romantics" as the first in an intended series, with a subtitle, but the ebook release was changed to "Secret Memoirs of Mary Shelley: Frankenstein Diaries" because the book is much more about Shelley than Frankenstein, who is not really much in the first book at all and was more about the series. So there are two covers for the paperback and the ebook. You can follow updates on the book and related stories about the Shelleys and the writing of Frankenstein at the blog website
