"The plague has hit Italy. Can Alana find the source in time to save the world? NATO infectious diseases expert Alana Vaughn receives an urgent message from an ex-lover, summoning her to Genoa to examine a critically ill patient. She's stunned to discover that it's the plague. Alana soon suspects bioterrorism, but her WHO counterpart, Byron Menke, disagrees. In their desperate hunt to track down Patient Zero, they stumble across an 800-year-old monastery and a medieval journal that might hold the secret to the present-day outbreak. With the lethal disease spreading fast, and no end in sight, it's a race against time to uncover the truth before millions die.-- Provided by publisher.
