James P. Hogan, Translated by Hiroshi Ike [Nebula Award Winner] A lunar surveyor discovers the corpse of a man in a crimson spacesuit. Meticulous investigation reveals that the body has been dead for 50,000 years. What is the connection to modern humans? Eventually, the wreckage of a spaceship not of Earth origin is discovered on Ganymede, a moon of Jupiter... This is the breakthrough work that made a new star of hard SF a sensation. First edition, 1980, with obi. Some soiling. Scratches and stains around the cover, stains and slight yellowing on the three sides of the book. No problem for reading. #SF #SogenSF #Hogan
