A single mother, Julie Broadrick doesn't know how to tell her two young children, seven-year-old Lisa and five-year-old Jimmy, that she has cancer and has only a short time to live. But a fluke accident on a camping trip gives her new life-not only are her injuries miraculously cured, but her lung cancer is gone and she has no desire to drink or smoke. That "miracle" was performed by Joe Murdock, who has discovered an advanced technology installation left by aliens more than four thousand years ago. Joe falls in love with Julie, and they become a family. Together, they recruit an eclectic group of scientists and adventurers-including aliens-to use the technology to conduct humanitarian work on earth and to explore space. However, their mission is threatened. Unknown forces have hatched a plot to destroy humanity and the earth. Joe, Julie, Lisa, Jimmy, and their cohorts must work quickly to identify the threat and shut it down before the earth is destroyed.
