Happy Independence Day. You’re all going to die. Life can’t be better for veteran pilot Larry Walder. He has a great job, a terrific kid, a gorgeous wife—and no inkling that tonight will be the end of the world as he knows it. In the early hours before the Fourth of July, three men break into Larry’s home. And as the day lurches on to its terrifying course, a life is taken, and Flight 816 from Atlanta to Cozumel, Mexico, vanishes off the radar. In the air, Larry must find a way to save his family, his crew, and his passengers. On the ground, disgraced FBI agent Xanadu Marx goes rogue, making it her mission to track down the missing flight before the hijackers reach their diabolical endgame. With the casualties racking up and the world’s busiest airport under lockdown, a message arrives: This is no ordinary hijacking, no typical hostage crisis. This ransom is a totally different beast—the first hint of a conspiracy that might bring America to its knees.
