No one believes ten-year-old Patricia Cromwell when she says that her parents were killed by a mysterious wormhole that disappeared as quickly as it formed. Likewise, twenty years later, no one believes thirty-year-old Patricia Cromwell, Ph.D. in radio astronomy, when she gives a presentation of her research into Long Delayed Echo (LDE) radio signals indicating alien transmissions. Patricia quickly discovers that Earth coordinates hidden in the radio message point to a Zinc mine in Alaska. Determined to see this through, Patricia cashes out her life savings and with some "borrowed" lab equipment, heads for the frozen northland. Sneaking into the Alaskan mining complex at night, Patricia discovers a hidden entrance leading to an underground alien ore processing center. Her insatiable curiosity leads her on an unimaginable trip through space and time to an Alien world on the brink of destruction.

Ultimately, the alien's actions put the survival of both worlds in Patricia's hands.
