Fifty Shades of Grey author EL James is returning with a new erotic novel.

The book, titled The Mister, is scheduled to be released on April 16, the Vintage Books publishing imprint announced on Thursday.

The Mister, which James has described as a “21st-century Cinderella”, features a rich Londoner who “has rarely slept alone” and a beautiful woman who is an “alluring mystery”.

James says The Mister is a “thrilling and sensual” fairy tale.

It comes almost eight years after the release of the original Fifty Shades of Grey book, which turned into a billion-dollar movie franchise and launched James’s career.

The Fifty Shades series originally consisted of a trilogy, but two more books have since followed.

James’s Fifty Shades books have sold more than 100 million copies around the world.
