Perelandra is the C.S. Lewis science-fiction novel set on the planet Perelandra. Published in 1943, it is the second volume of his Space Trilogy, following Out of the Silent Planet.
The novel again features Elwin Ransom, who travels to Perelandra, also identified with Venus. There he encounters a newly created world, its first inhabitants, and a conflict involving temptation and the future moral direction of the planet.
The trilogy is not a straightforward space-opera sequence. Lewis uses its planetary settings to explore theological and philosophical questions, including free will, corruption, obedience, and the meaning of civilization. The imaginative worlds serve as laboratories for those ideas.
The final volume, That Hideous Strength, appeared in 1945 and shifts much of its action to Earth. Because the trilogy’s books have different settings and tones, readers sometimes remember the planets but confuse which title belongs to which world.
