C.S. Lewis's 'Perelandra' sends Dr Elwin Ransom to Venus, an unfallen paradise. He must help its queen resist temptation as evil tries to cause a new Fall on this innocent world.
C.S. Lewis's 'Out of the Silent Planet' follows Dr Elwin Ransom as he is kidnapped and taken to Mars. There he discovers an unfallen, harmonious world and sees the fallen state of Earth from a new perspective.
