“Virus hunter” Christopher Dicken is a man on a mission, following a trail of rumors, government cover-ups, and dead bodies around the globe in search of a mysterious disease that strikes only pregnant women and invariably results in miscarriage. But when Dicken finds what he’s looking for, the answer proves to be stranger—and far deadlier—than he ever could have imagined. Something that has slept in human DNA for millions of years is waking up. Molecular biologist Kaye Lang has spent her career tracing ancient retroviruses in the human genome. She believes these microscopic fossils can come to life again. But when Dicken’s discovery becomes public, Lang’s theory suddenly turns to chilling fact. As the outbreak of this terrifying disease threatens to become a deadly epidemic, Dicken and Lang must race against time to assemble the pieces of a puzzle only they are equipped to solve—an evolutionary puzzle that will determine the future of the human race . . . if a future exists at all.

Eleven years have passed since SHEVA, an ancient retrovirus, was discovered in human DNA—a retrovirus that caused mutations in the human genome and heralded the arrival of a new wave of genetically enhanced humans. Now these changed children have reached adolescence . . . and face a world that is outraged about their very existence. For these special youths, possessed of remarkable, advanced traits that mark a major turning point in human development, are also ticking time bombs harboring hosts of viruses that could exterminate the “old” human race. Fear and hatred of the virus children have made them a persecuted underclass, quarantined by the government in special “schools,” targeted by federally sanctioned bounty hunters, and demonized by hysterical segments of the population. But pockets of resistance have sprung up among those opposed to treating the children like dangerous diseases—and who fear the worst if the government’s draconian measures are carried to their extreme. Scientists Kaye Lang and Mitch Rafelson are part of this small but determined minority. Once at the forefront of the discovery and study of the SHEVA outbreak, they now live as virtual exiles in the Virginia suburbs with their daughter, Stella—a bright, inquisitive virus child who is quickly maturing, straining to break free of the protective world her parents have built around her, and eager to seek out others of her kind. But for all their precautions, Kaye, Mitch, and Stella have not slipped below the government’s radar. The agencies fanatically devoted to segregating and controlling the new-breed children monitor their every move—watching and waiting for the opportunity to strike the next blow in their escalating war to preserve “humankind” at any cost.
