Humanity put all its fading hopes in New Eden, a pristine star system 230 light-years from the ravaged Earth. But upon arrival, the would-be colonists encountered the Kresh—a diabolical alien race who quickly captured the human starship and tortured its inhabitants in hopes of learning the coordinates of Earth.

Street-smart Cyrus Gant managed to escape, crashing to the surface of a nearby moon terraformed by the Kresh and inhabited by primitive humans. Now Cyrus pursues a desperate hope bound up in a single boy, a prophesized psionic named Klane—already in the clutches of the Kresh. Soon Cyrus finds himself torn between tracking down this so-called savior and escaping back into space before it's too late. Yet as he gathers allies and firepower, he's desperate to find a way back to Earth and warn them of this alien menace…only to discover an even greater danger to the future existence of the human race.

The electric interstellar action that began in Alien Honor continues in Alien Shores.
