'Mommy porn' Fifty Shades outsells Harry Potter on UK website

London, August 2 (ANI): EL James' 'Fifty Shades' trilogy has officially beaten JK Rowling's 'Harry Potter' series on Amazon's UK site, after just four months of sale.

James has sold more than four million copies of her novels in print and on Kindle since the books went on sale in March, making her the bestselling author of all time at Amazon.co.uk.

JK Rowling's final book in the Potter series, ' Harry Potter and the Deathly Hallows,' is being outsold by the first book in the James' trilogy, ' Fifty Shades of Grey,' by more than two books to one on the website.

"If JK Rowling was the literary phenomenon of the last decade, then EL James looks certain to take that mantle in the current decade," the Guardian quoted EU director of Kindle Gordon Willoughby as saying.

"In just four months, EL James has become Amazon.co.uk's biggest-selling author of all time, which is truly remarkable when you consider that we've been selling books for almost 14 years," he said. (ANI)
