“GRIPPING AND GRITTY.”—Richard North Patterson, #1 New York Times bestselling authorA school under siege. A shooter in the classroom. An all too common American nightmare unleashed again. But this time, former Delta Captain Jake Mahegan happens to be on the schoolgrounds checking in on the daughter of a colleague. Instead he’s staring down a suicidal gunman rigged to blow. During the standoff another attack begins outside the school. The gunman goes down, Mahegan is knocked unconscious, and a twelve-year-old autistic girl is kidnapped. Mahegan knows his mission before the smoke clears, but where it takes him is unimaginable—deep into a widespread conspiracy that threatens the nation’s very core. Treason in the highest halls of government. And only one man is prepared to stop it—or die trying . . .“An explosive, seat-of-your-pants thriller!” —W.E.B. Griffin and W.E.
