A diffident catering company owner, Max Rosen, learns of the existence of a coded research document authored by her late scientist father. This research is linked to health pills that were unearthed from the site of the Indus Valley Civilization in ancient India.

In a thrilling ride that takes her and Julian McIntosh, a history professor, across the world, she must keep her wits about her or face dire consequences at the hands of Berliner and other unknown forces, who will stop at nothing to keep the research from coming out. Even as she struggles with her feelings for Julian, Max must brace herself for startling discoveries -her father’s research may well reveal a frightening truth connecting Berliner, her grandfather, and perchance, all mankind. And the shocking reality about her father’s death is one she may never be able to face.
