After her journalist husband and infant son are brutally executed in a fire in their Florida home, photographer Harper McDaniel has nothing left to live for—except settling the score. When the local police fail to take the arson seriously, Harper takes the reins and discovers her husband was investigating some mysterious deaths at a cacao plantation on the Ivory Coast. Now she’s convinced he was targeted in a corporate conspiracy to silence him.

Aided by her former mafioso grandfather and well-connected financier brother, Harper embarks on a global manhunt, flying first to Africa, then Zurich to expose a high-level cover-up inside a powerful chocolate conglomerate.

But Harper has a few secrets of her own—starting with her lethal martial arts skills—and she’s not afraid to take on any hired guns or guerrillas standing in her way. In trying to cover their tracks, the conspirators made one fatal miscalculation: they didn’t count on Harper McDaniel coming for them.
