20,000 years from now, a space ship from the human colonies of the Lesser Magellanic Clouds accidentally falls into a time trap set up by two unimaginably powerful rival empires from millions of years in the future. The ship is thrown back 200 million years into the past. Will its Captain, the heroic Varun Shangrin, succeed in returning to their own time? And how did the accident affect the time war between the two shadowy cosmic combatants? Gerard Klein is a distinguished economist and one of France's best known science fiction writers. He also edited the prestigious science fiction imprint Ailleurs et Demain for 40 years. This new edition of this classic SF novel from 1965 also includes four short stories translated by SF Grand Master Damon Knight, and an introduction and bibliography by Jean-Marc Lofficier.
