In this gripping debut thriller from James M. Tabor, a brilliant and beautiful scientist and a mysterious special ops soldier must lead a team deep into the Earth on a desperate hunt for the cure to a deadly epidemic. When she was unjustly fired from a clandestine government laboratory, microbiologist Hallie Leland swore she would never look back. But she can't ignore an urgent summons from the White House to reenter the realm of cutting-edge science and dangerous secrets. " """Potentially the worst threat since Pearl Harbor"" is how the president describes a mysterious epidemic killing American soldiers in Afghanistan--and now poised for outbreak in the States and beyond. Millions will die unless Hallie and a hastily mobilized team can recover the ultrarare organism needed to create a new antibiotic. The good news is that Hallie knows more about the organism than anyone else on the planet.
