Mace Harper kills men; deadly, powerful men. In Iraq, the Marines reserved his elite sniper skills for the war’s grittiest missions. When he led his team off-reservation with an unsanctioned kill, the Corps sacrificed him to the CIA. Now this American pariah survives as an Infidel hunter of men in Pakistan’s savage Northwest Frontier.Years into this hard-bitten existence, his handler offers to trade permanent duty in the States for wet-work on elusive foreign terrorists. Harper leaps headlong into the Faustian gamble. He kills three Black Kings, his call-sign for enemy targets, only to be trapped in a fearsome double cross. He survives by the slimmest margin, disappearing into the invisible underbelly of Paris with a half million Euros, festering wounds and a trove of captured Intel.Then terrorists detonate twin cooling towers of a U.S. atomic energy plant and the captured Intel contains clues to the attack, along with possible home-grown involvement. Guilt and rage transform this discarded Marine sniper into a stone-sober predator hot on the trail of a hidden menace.
