Does the world really need a writing guide inspired by a Twilight fanfic?

E.L. James seemingly intends to milk that cash cow dry: according to Vanity Fair, a "how-to-guide" called Fifty Shades of Grey: Inner Goddess (A Journal) is due out in May, and will feature a mix of James’s writing tips, excerpts from the Fifty Shades books, and blank, lined pages for readers to explore their own "inner goddesses".

Whatever that means.
