The Space Trilogy

by C. S. Lewis · 2012

The Space Trilogy, also known as the Cosmic or Ransom Trilogy, is a three‑book series of science‑fiction/fantasy by C. S. Lewis. The novels follow Cambridge philologist Elwin Ransom as he is abducted to Mars (Malacandra) in *Out of the Silent Planet* (1938), sent to the pristine world of Venus (Perelandra) in *Perelandra* (1943), and returns to Earth to confront a sinister scientific organization in *That Hideous Strength* (1945). Across the books Lewis blends Christian theology, myth, and philosophical inquiry, presenting a cosmic battle between good and evil, the fall of humanity, and the possibility of redemption. The series is celebrated for its imaginative world‑building, poetic language, and moral depth, and it remains a classic of mid‑20th‑century speculative fiction.
