The final book in C. S. Lewis's acclaimed Space Trilogy, which includes "Out of the Silent Planet" and "Perelandra, That Hideous Strength" concludes the adventures of the matchless Dr. Ransom. The dark forces that were repulsed in "Out of the Silent Planet" and "Perelandra" are massed for an assault on the planet Earth itself. Word is on the wind that the mighty wizard Merlin has come back to the land of the living after many centuries, holding the key to ultimate power for that force which can find him and bend him to its will. A sinister technocratic organization is gaining power throughout Europe with a plan to "recondition" society, and it is up to Ransom and his friends to squelch this threat by applying age-old wisdom to a new universe dominated by science. The two groups struggle to a climactic resolution that brings the Space Trilogy to a magnificent, crashing close.
