Kyle Mills (Vince Flynn) Books in Order

The books grouped under this heading cover the stretch of the Mitch Rapp saga written by Kyle Mills after Vince Flynn’s death. Rather than rebooting the franchise, Mills stepped in mid-stream, picking up open threads from The Last Man and carrying them forward so the series felt continuous to longtime readers.

He begins with The Survivor, in which leaked CIA files and the legacy of traitorous operative Joe Rickman threaten to unravel years of covert work. From there, Order to Kill pushes Rapp into a deadly hunt for Pakistani nuclear weapons while Russia quietly maneuvers in the background, and Enemy of the State forces him off the books to deal with Saudi royals whose private support for terrorism collides with American political compromises.

With Red War, Mills widens the canvas even more. A Russian president facing a terminal illness tries to cling to power by engineering a confrontation with NATO, and Rapp is sent into the heart of that system to stop a conflict that could spill far beyond spycraft. The tone stays grounded in field work and small teams even as the stakes expand to near-global war.

Later entries turn to twenty-first-century vulnerabilities. Lethal Agent pits Rapp against an ISIS bioweapon and a virus being weaponized in the middle of political infighting in Washington. Total Power imagines what happens when terrorists actually succeed in taking down the American power grid, leaving Rapp to chase the people responsible in a country sliding toward chaos and scarcity.

In Enemy at the Gates and Oath of Loyalty, the danger comes closer to home. A new U.S. president, Anthony Cook, is deeply suspicious of both Rapp and CIA director Irene Kennedy. Rapp is tasked with protecting tech billionaire Nicholas Ward from an unseen enemy even as the administration quietly moves against him, and later must face Legion, a faceless assassin collective that cannot easily be called off. These books dig into the uneasy relationship between independent operators like Rapp and leaders who prize control above all else.

Throughout this run, Mills keeps Mitch recognizably himself—efficient, relentless, and loyal to a small circle of people he trusts—while acknowledging the wear and tear of decades spent in the field. The result is a continuation that honors Flynn’s original vision but isn’t afraid to explore new political terrain, making this era of the series feel both familiar and sharply current.
