The perpetrators appear to be American but are actually covert agents in a vast network of terror, selected and trained for one purpose only: the complete annihilation of America.

A few years after quitting his job to follow an ill-advised dream of becoming a guide on the Colorado River, Kevin Fedarko was approached by his friend, the National Geographic photographer Pete McBride, with a vision as bold as it was harebrained. Together, they would embark on an end-to-end traverse of the Grand Canyon, a journey that, McBride promised, would be “a walk in the park.” Against his better judgment, Fedarko agreed to the scheme. The ensuing ordeal, which lasted more than a year, revealed a place that was richer, and far more complex, than anything the two men had imagined.

Both are drawn into a race against time to stop the plot of an American bin Laden and prevent a global catastrophe.

Airport Ranger volunteer Stacy Broussard expected a peaceful Saturday morning ride around the perimeter of Houston's airport. What she encounters instead is a brutal homicide and a baffling mystery. Next to the body is an injured dog, the dead man's motorcycle, and a drone armed with a laser capable of taking down a 747. Though FBI Special Agent Alex LeBlanc sees a clear-cut case of terrorism, his past has taught him to be suspicious of everyone, even witnesses. Even bleeding-heart veterinarians like Stacy.
