I'M NOT HUMAN CASE. She smiled, a little shyly.
She's delusional, I thought.

We can understand the skepticism of Case Smithson, a self-described non-famous, science writer and radio talk show host, when confronted by this revelation from a beautiful young girl he'd met in a bar only an hour before. A girl whose personality seemed to change from moment to moment, from sultry Scandinavian seductiveness, to cool analytical brilliance, to hurt little girl. And what about this story of hers that she traveled all the way from Norway to Louisville, Kentucky, to see him, whom she'd never met, or even spoken to; and that a mysterious "they" were pursuing her? And what was her connection to Norwegian geneticist Lars Rasmussen, who Case knew only slightly, having never met the man in person?

Join Case and his lovely mistress, Brianne Devries, MD, on a chase that spans a continent and ends in a deadly confrontation, as they attempt to solve the Chinese puzzle that they know only as IV57384, or Ivy.
