alaxy. Humanity was slowly making their way out from Earth to the planets and asteroids of the Solar System, exploring and mining and founding colonies. The mining ship El Cavador is far out from Earth, in the deeps of the Kuiper Belt, beyond Pluto. Other mining ships, and the families that live on them, are few and far between this far out. So when El Cavador's telescopes pick up a fast-moving object coming in-system, it's hard to know what to make of it. It's massive and moving at a significant fraction of the speed of light.

They first appear as a series of dots on astronomical plates, heading from Saturn directly toward Earth. Since the ringed planet carries no life, scientists deduce the mysterious ship to be a visitor from another star. The world's frantic efforts to signal the aliens go unanswered. The first contact is hostile: the invaders blast a Soviet space station, seize the survivors, and then destroy every dam and installation on Earth with a hail of asteriods.

The planet attracted unwary travelers, hardened space-sailors, and merchant buccaneers - a teeming, constantly shifting horde that provided a comfortable income for certain quick-witted fellows like Flinx and his pet flying snake Pip.

Roger Torraway watched in horror as the monster lurched, toppled over and died. Project Man Plus had gone suddenly and drastically wrong. The race to colonize Mars was too important, too costly, and America was already too committed, for plans to be scrapped. They would have to make a new Martian. And Roger Torraway was it, candidate for the endless surgery, operation after painful operation, that would enable him to survive on that faraway planet.

Stoner knew. The fiery object hurtling toward the Earth was an alien spacecraft. But the world might never know. He was trapped in an iron cordon of secrecy, for the discovery had shattered the world power balance, setting off a brutal struggle for supremacy that raged from the sacred halls of the Vatican to the corridors of the Kremlin and the Pentagon. The forces of fear and treachery would use any weapon at their command, from mind war to sabotage, to keep the world in darkness.

But unlike Randolph, he does not care if Earth perishes in the process.

Six-time Hugo Award winner Bova likes to tell big stories in a small way. This approach both helps and hurts in this collection of stories, excerpts and outtakes from his "Grand Tour" novels (Saturn, etc.), which explore the colonization of the solar system. Despite his vast subject, Bova focuses tightly on the heroes and villains whose striving makes up his future history. While some characters are standards of the SF genre (megalomaniac capitalist, lone-wolf entrepreneur, love object caught between them), Bova imbues each with Homeric virtues and flaws.

T. Barnum, and the raging hormones of a teenage boy, Sam is the finest astronaut NASA ever trained and dumped. But more than money, more than women, Sam Gunn loves justice—and he really does love money and women.
