The Judas Strain (Sigma Force, Bk. 4)

From the depths of the Indian Ocean, a horrific plague has arisen to devastate humankind - a disease that's unknown, unstoppable . . . and deadly. Aboard a cruise liner transformed into a makeshift hospital, Dr. Lisa Cummings and Monk Kokkalis - operatives of the shadowy covert organization SIGMA Force - search for answers to the bizarre affliction that has inexplicably washed ashore. But there are others with far less altruistic intentions. In a savage and sudden coup, terrorists hijack the vessel, turning a mercy ship into a floating bio-weapons lab. At a Fourth of July celebration a world away, SIGMA's commander Gray Pierce thwarts the murderous schemes of a beautiful assassin - a would-be killer who holds the first clue to the discovery of a possible cure. With the fate of every man, woman, and child on Earth hanging in the balance, Pierce joins forces with the woman who wanted him dead, and together they embark upon an astonishing quest.
