Venus in Flames (STAR-DUST 27)

Sigurd/Marvin cannot leave the past. He suddenly finds himself in a 25-year-old body and in the captivity of the aliens. Only now does his fight for survival begin in a world of chaos that threatens to be torn apart by the battle between two alien power groups. The 'Guardians of the Stars' have suddenly become his henchman. They are trying to get hold of him, while GLEESITT, the 'City of a Thousand Stars' seems to be on his side. When the second group of aliens from Earth launch an attack on the mothership Ko and on GLEESITT, he must decide which side he is on.
