The American Mercenary series follows David Rivers after he leaves the military under a cloud and enters the world of private military contracting. Greatest Enemy (2016) launches the series, and 11 books trace Rivers’ transformation from a man with nothing to lose into a skilled operator navigating the dangerous world of off-the-books warfare.
The series builds through Offer of Revenge, Dark Redemption, and Vengeance Calling before reaching its conclusion. Kasper’s military background gives the action sequences a level of tactical detail that sets the series apart from typical military thrillers.
