A nuclear warhead detonated at 300 miles above the center of the United States would effectively take out the entire electrical grid and infrastructure of the 48 contiguous states. Most people don’t think this is a possibility. But what if it is? What if a country like North Korea actually has the capability to do this but has led us to believe they don’t? What if they had acquired stealth technology that would let them launch a missile that we didn’t know about until it was too late to stop it?

Clint Redshaw walks into a port facility meeting expecting an ordinary day arguing about the budget. When the shaking starts, he keeps calm. But as the tremors stretch on and on, the ground rips apart, the dock disintegrates, and chunks of land fall into the Strait. When the quake finally ends, there's only one thing on his mind: his daughter. Mika's singing songs and laughing with a gaggle of other sixteen-year-olds as they climb into the Pacific Northwest mountains for a scout weekend. One minute, it's sunshine and good vibes, and the next, it's screaming and chaos.

The day is like any other day until it becomes The Day. At 4:05 pm the United States is attacked with an electromagnetic pulse (EMP) weapon. A 20-megaton nuclear warhead is detonated high in the atmosphere above Kansas, blanketing most of the contiguous United States and parts of Canada and Mexico with an electromagnetic pulse that damages nearly all microprocessors and electronic controls beyond repair. Nearly every system that depends on computers and electronics has ceased to work.

Ripped from the headlines, the explosive Trackers saga is a realistic depiction of what an EMP attack and the aftermath might look like from one of the genre's leading voices, USA Today best-selling author and former Homeland Security disaster mitigation officer Nicholas Sansbury Smith. This box set includes the entire four-book Trackers series with over 30 hours of post-apocalyptic survival fiction and action. This box set includes Trackers, Trackers 2: The Hunted, Trackers 3: The Storm, and Trackers 4: The Damned.

Jason Sterling had a simple life by all accounts. He had worked the same job his entire adult life, he had never married, and he had no children. He was used to doing things on his own. His comfortable life was shaken to the core the day he learned of his fathers death. It was a mysterious meeting that set life-altering events in motion, and the allure of a new life was too great to walk away from. When an electromagnetic pulse brings the modern world to its knees, Jason's choice proves to be the right one.
