“‘Of course,’ said Orfieu, ‘the sort of time-travelling you read about in books—time-travelling in the body—is absolutely impossible.’” So begins The Dark Tower, a captivating novella that continues the adventures of Dr. Elwin Ransom after the events of Out of the Silent Planet, the first novel is Lewis’s Space Trilogy. In Orfieu’s office at Cambridge University, five men gather to witness the breach of space-time through the chronoscope, a telescope that looks not just into another world, but into another time. Also included are "After Ten Years," Lewis’s retelling of Menelaus’s battle for Helen, "The Man Born Blind," the story of a man who after gaining sight for the first time in his life learns about the relative nature of reality, and three other short stories. A necessary anthology for fans of futuristic fiction, this collection cements Lewis’s place in the science fiction canon.
