“Fifty Shades of Grey” is no longer atop the best-seller list. That honor goes to a book that won’t be in stores until next week. “No Easy Day” is written by a former member of SEAL Team Six about that fateful day when they took down Osama bin Laden.

People are eager to read the first-hand account of that dangerous mission back in May of last year. The book has become so popular that the original sales date had to be moved up a week. The initial idea was to release "No Easy Day" on September 11th.

Fox News and the Associated Press have identified the “anonymous” author as Matt Bissonette, who was a member of SEAL Team Six.
