Space: 1999 the Forsaken

"A mysterious signal is intercepted... The collective voice of a dying race... A plaintive call to forces beyond human ken. Yet int the ruins of a civilization... hope. A chance for a new life, a new home? Or a deception...? Sinster forces are still at work. Forces of destruction and genocide. That transform Alphans ... into Angels of Death" -- Unedited summary from the book.
