Fox News says it has unmasked the former commando behind a forthcoming book that promises first-hand details of the Navy SEAL mission last May that led to the death of Osama bin Laden.

The book, No Easy Day: The Firsthand Account of the Mission That Killed Osama bin Laden, is due out September 11 (natch) from Dutton, an imprint of Penguin. The volume’s jacket will carry the pseudonym “Mark Owen,” but Fox reports that it has learned that the author’s real name is Matt Bissonnette. (No Easy Day was co-written by Kevin Maurer, an author who has published previous books about special forces operations.)

Owen, or Bissonnette, was a member of the SEAL’s Team 6, an elite unit responsible for the bin Laden raid as well as other high-profile missions such as the April 2009 rescue of the crew of the freighter Maersk Alabama from pirates off the coast of Somalia.

Bissonnett’s recounting of what happened that night in Abbottabad, Pakistan, when SEALs stormed bin Laden’s compound and offed the Al Qaeda leader will surely be a hot seller, but its imminent publication might have the author in a bit of trouble with his former bosses. The Pentagon and CIA often take a first pass at books by former officials and soldiers with knowledge of top-secret information. No such vetting was done in Bissonnette’s case, Fox reports:

Lt. Cmdr. Chris Servello, a Navy spokesman, said it’s possible Bissonnette or any former service member could be punished for revealing national security secrets. “Any service member who discloses classified or sensitive information could be subject to prosecution—this doesn’t end when you leave the service,” Servello said. “There is nothing unique to the special warfare community in this regard.”

No Easy Day won’t be the first detailed retelling of the Abbottabad raid—The New Yorker published a detailed account last August based on quotes from officers who debriefed SEAL operatives—but it is the first to promise a first-hand version.
