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 humans from all over Earth into its interior. There they discovered that Keanu was a long-range spaceship—and they were not alone. 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.
For when Keanu reestablished contact with Earth, they learned that the Reivers have taken over the planet, placing most of the population under their dominion. But mankind's last hope may yet be hidden inside the NEO. And if the men and women still in Keanu cannot find it, humanity will be finished. And the galaxy will be next.
