When it first appeared, the astronomers named the asteroid Keanu.

A Near Earth Object, from a distant constellation, it was headed directly toward our sun.

But when we went to meet it, it turned out to be far more than a huge rock hurtling through space...

The two teams of astronauts sent to explore Keanu discovered it is, in fact, a spacecraft, a giant ship with an alien crew. 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...

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. And the message is: Help us.
