Seth Walker

Still reeling from a devastating personal tragedy, air marshal turned investigator Seth Walker embarks on his first case. All he has to do is accompany female pop star Max Magic to Los Angeles and deliver her to the FBI. But when their routine flight ends in a hail of gunfire at LAX, Walker has no choice but to take the frightened diva on the run.

A commuter flight has fallen from clear skies over West Virginia, its wing sheared off at 20,000 feet. Air marshal Seth Walker is called to the mountains of Appalachia to investigate. But what he stumbles into is a ground war as unpredictable and combustible as a mason jar full of nitroglycerin. Before he can even start searching for what might have downed the plane, Walker finds himself caught in the confounding - and deadly - cross fire between drone-deploying ecoterrorists, unstable frackers, ruthless drug smugglers, and armed miners pushed to the breaking point.

When an electrical engineer from one of America’s premier tech companies disappears inside the San Francisco International Airport before an overseas flight, air marshal Seth Walker is called in to investigate. With the clock ticking down and questions multiplying at every turn, Walker can’t afford to fail: the lives of all two hundred thousand passengers inside SFO may hang in the balance. As he races through crowded concourses, desperately searching for clues, Walker can sense this is no routine missing-persons case.
