The science fiction epic of our time has arrived.Three years ago, an object one hundred miles across was spotted on a trajectory for Earth's sun. Now, its journey is almost over. As it approaches, two competing manned vehicles race through almost half a million kilometers of space to reach it first. But when they both arrive on the entity, they learn that it has been sent toward Earth for a reason. An intelligent race is desperately attempting to communicate with our primitive species... moreThe science fiction epic of our time has arrived.Three years ago, an object one hundred miles across was spotted on a trajectory for Earth's sun.

A ship that had headed to Earth with a mission and a message: Help Us. A brave new frontier beckons. But we are about to learn that it comes with a price...Without warning, the aliens transport small groups of humans from the competing scientific communities of Houston, Texas and Bangalore, India to the vast interior habitats of Keanu. Their first challenge is to survive. Their second; to discover why The Architects—the unknown, unseen aliens controlling the asteroid—brought them there. And soon a third emerges: they must find a way to take control of Keanu.Because the NEO is moving again—away from Earth. The Architects are headed home... less

Mankind’s first contact with extraterrestrial life led to an incredible revelation. Their last may lead them to extinction. Twenty years have passed since the mysterious Near-Earth Object nicknamed Keanu appeared in the night sky and transported an assortment of humans from all over Earth into its interior. There they discovered that Keanu was an immense long-range spaceship—and they were not its only inhabitants... moreMankind’s first contact with extraterrestrial life led to an incredible revelation. Their last may lead them to extinction. Twenty years have passed since the mysterious Near-Earth Object nicknamed Keanu appeared in the night sky and transported an assortment of humans from all over Earth into its interior. There they discovered that Keanu was an immense long-range spaceship—and they were not its only inhabitants. They joined forces with the aliens called the Architects, who had come from a distant galaxy to seek help in fighting the vicious Reivers. And they defeated them—or so they thought.Now Keanu has reestablished contact with Earth—and discovered that the Reivers have, in fact, taken over the planet, placing most of the population under their dominion. A few scattered pockets of humanity, constantly in danger of being assimilated, have mounted a resistance.As the Reivers prepare a devastating strike against the Architects, Rachel Stewart, who grew up in Keanu, leads a small band of human survivors in an attempt to infiltrate the massive Reiver fortress in the American West. But their only hope for victory may yet be somewhere inside the NEO.If the men and women still in Keanu cannot find it, humanity will be finished. And the galaxy will be next. less
