The aliens aren't coming. They're here. We've captured several of them. The human race can't decide. Are they our saviors or out to destroy us? The government has had no luck in their interrogation of their prisoners. We've seen no spaceships, received no ultimatums - but the aliens may have a more insidious plot...

Government agent Dan Dannerman, astronomer Patrice Adcock, and several others were kidnapped while investigating the aliens' presence on an orbital laboratory. They have now returned to Earth, but in altered states. Dannerman and Adcock have been cloned. All of them have been implanted with strange alien devices. Nobody knows exactly what happened to them during their abduction - or why they were taken - but Dannerman is determined to find out.

Suddenly the Dannermans, the Adcocks, and the government find themselves distracted by a rash of extremist threats and government attacks. But are they a reaction to the aliens' arrival - or are they a part of the aliens' plans?
