Wayne Robertson is an astrophysicist at a radio telescope array in Antarctica who intercepts a series of transmissions from over half a billion light years away, and 176 years into the future. It is through these transmissions that he discovers the existence of Maxim Akihiko Broussad, a deranged genetic hybrid named Spegg, and a wealth of new technology that could ultimately destroy the human race.
