A woman who doesn’t die.
A human who isn’t easy to kill.
A man who murders for power.
Dr. Mona Signoretti has the rare ability to shield her Infinitas life energy from others, making her appear human. She uses that talent by going undercover for a special FBI unit to investigate one of her species suspected of developing a deadly toxin to gain power in the human world. If she fails, not only are humans at risk, but also the mission to save her race from destruction. When her role is discovered and her life-sustaining energy threatened, an all-too-human agent, Grant Thornton, is assigned to keep her alive—not an easy task in a world where enemies refuse to die.
