The deadly Scorpius Syndrome has decimated North America.

With nothing but rumors to lead her, Dr. Lynne Harmony has trekked across a nightmare landscape to find one man—a mysterious, damaged legend who protects the weak and leads the strong. She believes she can find a cure, but she can't do it alone.
