It has been nearly 100 years since the Apollo moon landings, when Jack and Vladimir, two astronauts on a mission to Venus, discover a mysterious void related to indigenous life on the planet. Subsequently more voids are detected on Earth, Mars, Titan, and, quite ominously, inside a planetoid emerging from the Kuiper belt. Jack is sent to investigate the voids in the Solar System and intercept the planetoid - which, as becomes increasingly clear, is inhabited by alien life forms.

Space explorers and planet-bound scientists alike prepare for mankind's first encounter with alien intelligence.

But after narrowly surviving two assassination attempts when he brings evidence of the misdeeds to the capital star system, Geary realizes that some want to get rid of him.

Ian Stevens, director of the Deep Space Research Institute, isn’t interested in conducting research just for the sake of research. While the rest of the world - including the US Government - thinks that’s the DSRI’s sole mission, Stevens is actually interested in more - he wants manned space travel and the colonization of the moon. With NASA defunct, few scientific probes are being launched, and no one even talks about human spaceflight anymore. Stevens is out to change that.

2067 was the year I died for the first time. It was painful. Had I known how often I'd be expected to die over the next several millennia, I might have made a stronger effort to stay dead. The year actually started off rather nice. I finished my PhD in high energy physics and was promoted to lieutenant commander in the United States Air Force. My first posting after the promotion was to the Lunar One Air Base where I worked with my father, Dr. Robert Kimbridge, on "The Project".
