Fertilates: Chronicles of Galaxy Osmaron (Paperback) (ISBN-13: 9781068790249)

To save mankind, Sarah and others decided to contaminate Earth with the Terminal Disease. That disease only affected humanity and would prevent almost everyone from having children. The contagious disease was expected to remain until Earth's population decreased to below 500 million. That process would take close to 100 years.

Despite its ubiquitous presence throughout the planet, no symptoms would ever be detected or felt by the infected and humans could live out their normal lives, although without children. This situation leads to much unrest on Earth so Mallory is chosen to save the day.
