Which C.S. Lewis novel is the first book in his Ransom Trilogy, also called the Space Trilogy?

Out of the Silent Planet is the first novel in C.S. Lewis’s Ransom Trilogy, also called the Space Trilogy.

Published in 1938, the novel follows Elwin Ransom, a philologist who is abducted and taken to Malacandra, a planet readers can identify with Mars. Ransom’s knowledge of languages becomes crucial as he encounters intelligent species and tries to understand the society around him.

The second book, Perelandra, was published in 1943, and the third, That Hideous Strength, followed in 1945. Although the books share Ransom and a larger philosophical framework, each has a distinct setting and plot. The trilogy combines planetary adventure with questions about language, morality, science, and the misuse of power.

The word “Ransom” also creates a deliberate literary association with rescue and redemption. Lewis wrote the trilogy partly as an alternative to the darker scientific romances he felt were common in modern literature.
