Lord of the Spiders or Blades of Mars — Michael Moorcock

Journey to Anywhen!

Michael Kane had to return to Mars. The siren call of the ancient planet filled his blood with longing...both for a world that was not his own, and for the lovely Queen Shizala, the alien who claimed permanent possession of Kane's heart. But the way back lay through the matter transmitter, and the journey threatened to be more perilous than even Kane imagined! For the matter transmitter could not be controlled; when it tore him from Earth, the other end of his journey might be anyplace...or anywhen! And the Mars that he discovered this time was not the Mars of his Shizala! As perilous as his early adventures had been, this Mars was far more deadly and alien!
