Oath of Loyalty (A Mitch Rapp Novel Book 21)

Winner of Best Thriller of 2022 by The Real Book Spy

In this electrifying addition to Vince Flynn’s #1 New York Times bestselling series, Mitch Rapp faces a new kind of enemy—one he may not be able to stop.

With President Anthony Cook viewing him as a dire threat, CIA Director Irene Kennedy brokers a fragile truce: Rapp agrees to leave the country and remain visible as long as Cook remains in power. In return, the administration promises not to move against him.

But the uneasy peace shatters when Cook’s ruthless security adviser convinces him that Rapp has no intention of honoring their deal. To strike first, they expose the identity of Rapp’s partner, Claudia Gould, making her a target. As Rapp scrambles to protect her, he uncovers an even greater danger—a faceless, relentless assassin known only as Legion.

Operating under an airtight system of secrecy, Legion’s identity remains unknown even to their clients. Once a contract is placed, there is no calling it off. No matter how long it takes, the job won’t end until the target is dead.

With the world closing in around him, Rapp must outthink and outfight an enemy unlike any he has ever faced in this pulse-pounding thriller packed with nonstop action and political intrigue.
