At twenty-nine, research scientist Kate Denby was a workaholic, divorced, and the mother of an eight-year-old son. And she was weeks away from making a major genetic breakthrough. If she lived that long.... Danger has arrived in Kate's backyard with a vengeance, starting with an explosion at a Seattle pharmaceuticals plant and a car bombing at her son's Little League game. Then came the shocking warning: the attacks were connected and she was the next target. Stalked by a remorseless killer, Kate must put her trust in a total stranger, a man whose intentions are nearly impossible to fathom. For no matter what happens, she must protect her son and her work, the work that could save millions of lives. But someone will do anything to keep her miracle from unfolding. Someone not interested in holding out hope but in buying and selling death.
