It is the forty-first century. Falling prey to unimagined solar processes, the sun has exploded and destroyed the Earth. Thousands of survivors move outward into space aboard the Space Star Silver Streak. Thirteen years have passed as they search for habitable planets to colonize. Now, with the ship almost emptied, the mission nearly at an end, the most recently established colony signals distress. Something huge, ominous, mysterious, and inexplicable is wandering through the galaxy. Ten years ago Captain Richard Cameron resigned from command. Faced with a new and completely unexplained crisis, he returns to the bridge, reunites his old crew, and sets off on a voyage that may mean the end of his career or the salvation of civilization--or both! A voyage to the limits of knowledge, a voyage to the height of human potential...A voyage into the unknown!
