New York Times bestselling author Elizabeth Lowell cuts a new edge in suspense with a thrilling tale of passion and international intrigue. Emma Cross abandoned the blood, guilt, and tribal wars of CIA life for the elite security consulting firm St. Kilda's. Now she's tracking the yacht Blackbird, believed to be carrying a lethal cargo that will destroy a major American city . . . in just seven days. Emma's partner, MacKenzie Durand—a former special ops killer well-honed in the world's nastiest regions—is more dangerous and unpredictable than the worst enemy she's ever faced. And other eyes are watching Blackbird as well—cold and calculating, looking to alter the geopolitical balance through violence and terror. In a deadly game where the rules change without warning, Emma and Mac must find answers or watch the innocent die in unthinkable numbers. The race is on—and there's no telling who will cross the finish line alive . . .
