“Jason Kasper’s American Mercenary series boils with bold action, exotic locales, and spellbinding intrigue.” (Mark Greaney, number one New York Times best-selling author of the Gray Man series)

From former Special Forces officer Jason Kasper comes a gripping set of thrillers for fans of Vince Flynn and Brad Thor. Now an international best seller.

Book 1: Greatest Enemy 

Army Ranger David Rivers enters the covert underworld of ex-special operators for hire. His new team serves a faceless mastermind known as the Handler. But as the stakes continue to rise, he learns that his new employer is more ruthless than anyone he's faced in combat - and he just might be David's greatest enemy. 

Book 2: Offer of Revenge 

David Rivers wants vengeance. But to get it, he must join the secretive organization that slaughtered the only family he had. Sent into battle against a savage force of enemy fighters in Somalia, David realizes that someone inside the organization seems to know his true purpose...and has been waiting for him all along. 

Book 3: Dark Redemption 

The path to revenge leads David Rivers into a labyrinth of twisted loyalties in the violent slums of Rio de Janeiro - where he learns the betrayal of his team was just the beginning. And nothing in David’s murderous past can prepare him for what happens when he finally meets his greatest enemy face-to-face.

Perfect for fans of Mark Greaney, and Brad Taylor.
