Offer of Revenge
An avenging survivor. An unconquerable enemy. And one impossible betrayal...
David Rivers wants vengeance.
But there’s only one way to kill his greatest enemy―David must first join the secretive organization that slaughtered the only family he had.
To prove his allegiance, he enters a life-or-death battle in the badlands of Somalia.
But the closer David gets to his target, the more he realizes that the betrayal of his team was not as random as he thought.
Someone inside the organization seems to know his true purpose, and that could mean only one thing:
David might not have been the sole survivor after all.

Jason Kasper
Jason Kasper doesn’t write thrillers that let you breathe easy. He writes the kind that drag you into the shadows and keep you there, pulse ticking, until the final chapter. His work is a high-wire act of tension and authenticity—because he’s not just imagining danger. He’s lived it.
Before turning to fiction, Kasper served as a U.S. Army Special Forces officer, with combat deployments in Afghanistan and a firsthand understanding of the stakes behind the missions. That real-world experience bleeds through every page of his bestselling Shadow Strike and Spider Heist series. You can feel it in the precision of the action scenes, in the way his characters calculate risk and navigate chaos. These aren’t just thrillers—they’re field-tested adrenaline shots.
