The Rogue Intruder by F. W. Jamison
By the year 2147, mankind was living and working in space. To escape the savageness of Unigov, Dr. Timothy Grey and colleagues, with the help of BMW Mining, decided to build an interstellar spaceship and hide it next to BMW’s main mining facility in the asteroid belt. The spaceship was designed to take them and their future generations to Kepler-452c, Earth’s twin. However, before they could complete the spaceship, a small, rogue black hole racing toward the solar system was discovered by a teenage amateur astronomer.
Mankind now has eighty-one years to save itself. Can Dr. Grey and colleagues complete the spaceship and leave the solar system before Unigov can commandeer it, or will they perish in the inescapable annihilation?
