Our view
“That Hideous Strength” closes Lewis’s “Space Trilogy” on Earth, with a dark tale of a scientific institute fronting for supernatural forces. It follows a married couple, Jane and Mark, on separate paths: his reads like psychological horror relieved by flashes of farce, hers stays with her thoughts and feelings, and the alternation works. Some readers feel Lewis explains too much, and others do not grasp all of the ending. A very different book from the two before it.

About the book
That Hideous Strength: A Modern Fairy-Tale for Grown-Ups is a 1945 novel by C. S. Lewis, the final book in Lewis's theological science fiction Space Trilogy. The events of this novel follow those of Out of the Silent Planet and Perelandra and once again feature the philologist Elwin Ransom. Yet unlike the principal events of those two novels, the story takes place on Earth rather than elsewhere in the Solar System. The story involves an ostensibly scientific institute, the National Institute for Co-ordinated Experiments (N.I.C.E.), which is a front for sinister supernatural forces.
