E. L. James has another hit on her hands. The author’s latest book, Grey: Fifty Shades of Grey as Told by Christian, has sold more than 1.1 million copies in its first four days of release.

In a statement, publisher Anne Messitte said, “This is an astonishing number of books to sell over a weekend and speaks to the engagement and passion readers have for the Fifty Shades books.”

To meet demand, the publisher is running off third, fourth and fifth printings of Grey, bringing the total number of copies in print to 2.1 million.

James’s original erotica trilogy — Fifty Shades of Grey, Fifty Shades Darker and Fifty Shades Freed — has sold 125 million copies worldwide.
