A medical researcher comes face-to-face with the unfathomable love required to sacrifice an only son.

Jeremy Cramer, MD, is the Einstein of infectious disease research. While working on a way to revive water-submersion victims, he makes a breakthrough discover in AIDS research that thrusts him into the center of a media frenzy. But the publicity turns negative, and his marriage reaches the breaking point when he accidentally infects a colleague and his negligence allows his son to contract a life-threatening disease. The viruses test the limits of his new formula—and his ethics. In the midst of his frantic efforts to save his son and marriage, he must decide whether to allow his child to die or violate the rights of a young transplant donor.
