Fifty Shades of Grey, Fifty Shades Darker, and Fifty Shades Freed once again top The New York Times best seller list, with the erotic romances ranking in order of their release. The e-books by E.L. James have appeared on the Times’ combined print and e-book fiction list for the past 15 weeks. In fact, the books are so popular that James is reportedly considering writing a new trilogy told from the perspective of Christian Grey.

Gillian Flynn’s Gone Girl, a novel about a woman who disappears on her fifth wedding anniversary ranks fourth on the list, while Kiss the Dead, a vampire thriller by Laurell K. Hamilton, comes in at number five. Both books are new to the best seller list.

The Fifty Shades Trilogy, a bundle of all three Fifty Shades novels, fell from fifth place to sixth, while George R. R. Martin’s A Game of Thrones soared from fifteenth place to seventh. The renewed interest in A Game of Thrones, first published in 1996, is undoubtedly due to the hit HBO series by the same name.

James Patterson and Maxine Paetro’s 11th Hour, John Sanford’s Stolen Prey, and David Baldacci’s The Innocent round out the top ten best sellers. All three murder mysteries have appeared on the list for several weeks.

The rankings on the current list reflect sales for the week ending June 9. Check back in a couple of weeks to learn if the Fifty Shades trilogy continues to dominate The New York Times best seller list.
