Book Description for Book One: There is a dream called Moonbase, nurtured by ex-astronaut Paul Stavenger and his wife, Joanna Masterson Stavenger, head of the powerful Masterson Corporation. There is a future of astonishing possibilities and vital technological development waiting on a lifeless world of astonishing contrasts, where sub-frigid darkness abuts the blood-boiling light -- a future threatened by greed and jealousy, insanity and murder. The Moon and its mysteries have captivated the Stavenger family, and it will continue to exert its pull upon subsequent generations. For all those who experience its magnificent desolation are haunted by it eternally. Some will be doomed by its pitiless aversion to human life. And some can never leave.
