ju·das strain, n. A scientific term for an organism that drives an entire species to extinction New York Times bestselling author James Rollins returns with a terrifying story of an ancient menace reborn to plague the modern world . . . and of an impossible hope that lies hidden in the most shocking place imaginable: within the language of angels. From the depths of the Indian Ocean, a horrific plague has arisen to devastate humankind--a disease that's unknown, unstoppable . . . and deadly. But it is merely a harbinger of the doom that is to follow. Aboard a cruise liner transformed into a makeshift hospital, Dr. Lisa Cummings and Monk Kokkalis--operatives of SIGMA Force--search for answers to the bizarre affliction. But there are others with far less altruistic intentions.
