John Knox and Grace Chu, the incomparable duo of the Risk Agent novels, team up again in the latest international thrill ride from New York Times–bestselling author Ridley Pearson. When ex–military contractor John Knox receives a text from partner Grace Chu warning that she fears her cover may have been blown while on assignment, he jumps into action. Knox must locate her overseas handlers, convince them of the threat, and then attempt to retrace the well-hidden steps of a woman who had been attempting to determine how one million euros’ worth of AIDS vaccine disappeared, all while eluding angry poachers on a parallel trail. Corruption isn’t a “problem” in Kenya, it’s the way of doing business. The poaching of ivory from African elephants, driven by insatiable demand from mainland China, fuels constant blood and slaughter. Knox faces police, national rangers, journalists, and safari companies who are each in their own symbiotic relationship with elephants, both good and bad. As the threat from Al-Shaabab militants interferes with his pursuit of Grace, Knox finds himself pitted against the most savage and suicidal fighters in the world. And there’s this woman, Grace, always in his head. His gut. As Grace watches as her civilized self slips away while abandoned in the bush, Knox races against the clock to find her.
