'Fifty Shades Freed' most popular book on Amazon in 2012
E.L. James' erotic romance novel "Fifty Shades Freed: Book Three of the Fifty Shades Trilogy" was the best-selling book on Amazon this year, followed by the thriller "Gone Girl," the online retailer said on Friday.
"While E.L. James published the first two books in her Fifty Shades trilogy in 2011, so they aren't eligible for our 2012 list, the series really took off this year and propelled the third installment and the omnibus edition onto our Top 10 list," she added in a statement.
"The Marriage Bargain (Marriage to a Billionaire)" by Jennifer Probst was No. 6 and David Baldacci's "The Innocent" rounded out the Top 10.
