In the tradition of The Andromeda Strain and The Terminal Man, an up-to-the-minute medical thriller about an international struggle to develop a pill to make humans immune to nuclear radiation. The serum L-6 does work, but it has one devastating side effect: its users become soulless immortals.
Vandiver, a scientist at a government lab, is assigned to devise a serum to protect humans from nuclear radiation, but instead of inventing his own he steals that of his best friend, with terrifying consequences. Reissue.
