Which C.S. Lewis book forms the second volume of the Space Trilogy?

Perelandra forms the second volume of C.S. Lewis’s Space Trilogy. The novel was published in 1943, following Out of the Silent Planet and preceding That Hideous Strength.

The story sends the protagonist, Dr. Elwin Ransom, to the planet Perelandra, also known as Venus. There he becomes involved in a conflict concerning temptation, freedom, obedience, and the future of the world.

The trilogy is also called the Ransom Trilogy, after its central character. Although the books use interplanetary travel and speculative settings, they are not straightforward technological science fiction. Lewis uses the genre to explore theological and philosophical themes.

A common ordering mistake places That Hideous Strength second because its title is often more familiar to readers. The publication order is clear: Out of the Silent Planet appeared in 1938, Perelandra in 1943, and That Hideous Strength in 1945.
