Not since Pandemic have we seen a thriller like this from bestselling author Daniel Kalla: The plague has hit Italy. Can Dr. Alana Vaughn find the source in time to save the world? No person is left unscathed, no family untouched. Death grows insatiable. Alana Vaughn, an infectious diseases expert with NATO, is urgently summoned to Genoa by an ex-lover to examine a critically ill patient. She's stunned to discover that the illness is a recurrence of the Black Death. 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.
