It is the year 2044 on Earth. At the Farside observatory complex on the Moon, a startling astronomical discovery has been made. A survey for pulsars has found an x-ray source in a region of space where none has been detected before.
Upon further investigation, they find that this x-ray source is just outside of the Solar System. The astronomers are paralyzed by what they have found knowing what its disastrous ramifications might be.
A neutron star is approaching the Solar System. It appeared out of a small dust cloud that was shielding its approach. Armageddon has arrived; the star is on a trajectory that will take it through the center of the Solar System. Life on Earth will not survive its passing.
The only hope for survival will be on the massive Star One space station at the Earth-Moon Lagrange point or possibly in Tycho City deep beneath the Moon’s surface. It will be a race against time to save a fraction of the Earth’s frightened population.
A power struggle will erupt on Earth over who is to survive. On Star One and at Tycho City they prepare for the worst, unfortunately, the threat from Earth might be just as dangerous as the approaching neutron star.
This is a short story and not a full sized book. I would say that it can mostly be considered a teaser to the series which, currently, contains two full sized books depicting what follows after the events in this book. Actually, at least half of the books blurb above is more applicable to the following two books than this one.
As the title says this booklet deals with the actual discovery of the neutron star. If you feel you might be interested in the series it is indeed a good idea to read this one. Even though it is quite short it introduces some of the main characters, gives you some background as well as a good idea of the authors style of writing.
Personally I found it a good enough reading that I continued with the rest of the books in the series.
