Top Ten Best-Selling Ebooks -- Week of February 7

Just as predicted, the two E L James titles that debuted on last week's Digital Book World Ebook Best-Seller List jump up into the top ten this week.

The film adaptation of Fifty Shades of Grey is due to hit theaters on Valentine's Day, likely propelling two-thirds of James's trilogy up the rankings much the way the Bradley Cooper movie recently helped American Sniper into the No. 1 spot a few weeks ago.

The two other authors to score two titles on this week's list are Gillian Flynn and Harper Lee, whose forthcoming Go Set a Watchman and classic To Kill a Mockingbird are both back the in spotlight amid controversy surrounding the newly discovered work.
