Mase Colton has worked for years in the harsh unforgiving environment of the Moon building Tycho City. Now, with the completion of the Farside observatory complex, a deadly danger to the Moon and Earth has been discovered. A neutron star is about to enter the solar system. Can Mase Colton and his counterpart, Steve Larson on the Star One space station, find a way to preserve a small segment of humanity against this deadly danger? It's a race against time and the politicians on Earth who refuse to believe in the approaching neutron star as they struggle to save the human race. On Earth, fighting breaks out as the neutron star nears and chaos spreads across the globe. Lieutenant Trace Lewis will do whatever it takes to ensure his family survives the calamity. However, even his marine training hasn't prepared him for what's coming. This book contains an expanded version of Tycho City: Discovery as well as Tycho City: Survival.
