"Former CIA operative Kate Cavanaugh wasn’t prepared for her old boss to show up at Sandstorm International with her French counterpart and an unusual request: prevent the Frenchman’s daughter from joining the world’s most savage terrorist group in Syria. Kate is intrigued, husband Nick is opposed, and business partner Jake is up for anything. Over Nick’s objections, Kate reunites the Sandstorm family for a most unconventional operation in Istanbul, Turkey. Kate, Nick, and their team engage in an escalating series of psychological battles and provocations against Camille Dubois, whose devotion to the terrorists and their so-called caliphate, and all it represents, is unwavering."
