ENEMY WITHIN

The safe is unbreakable. The assassin unstoppable. The clock unforgiving.

When ex-special forces operative Danny Devlin is dragged from his quiet island retreat, he’s thrown into the deadliest mission of his life: infiltrate a high-security flight, crack an unbreakable safe midair, and steal the key to billions stolen from the world’s most dangerous criminals.

But Devlin isn’t the only predator circling. Ruthless mercenaries, a ghostlike assassin, and a storm of betrayal are closing in. Every move takes him deeper into a world where trust is a weapon—and survival means outwitting enemies who kill without hesitation.

Explosive, relentless, and razor-sharp, Enemy Within proves Danny Devlin is the kind of hero readers of Lee Child, Vince Flynn, and Jack Carr have been waiting for.
