On September 11th, Penguin’s Dutton Adult is publishing a first hand account of the killing of Osama Bin Laden. The title, No Easy Day: The Firsthand Account of the Mission That Killed Osama Bin Laden, was written by a member of the elite squad who killed the terrorist leader known as SEAL Team Six.

The title has been published under the pseudonym Mark Owen, but Fox News reported that they discovered his real identity.

The title is already shooting up the charts from presales. It is currently the No. 1 bestseller on Amazon, ahead of all of the Fifty Shades of Grey titles and the Publication Manual of the American Psychological Association.
