Tough-as-nails Bureau of American Defense agent Hunter Thornton-Payne is no stranger to uncomfortable top-secret missions, but tonight takes the cake. He just needs to stick out a stuffy charity fund-raiser long enough to find the ruthless assassin he's hunted for four years. It's a rogue operation, but Hunter's got nothing to lose—until a beautiful brunette unexpectedly pulls him into her own dangerous agenda. Abbie Blanton will do anything to cure her mother's mysterious illness. When a high-profile heiress is murdered as Abbie tries to blackmail her for clues, Abbie realizes she's stumbled into an unforgiving conspiracy—and she's the next target. Soon, she and Hunter discover an alarming connection and begin a treacherous battle against an evil enterprise that someone will go to terrifying lengths to keep hidden.
