“The Future Happens Twice” is an exciting science fiction novel about a clandestine government program aimed at sending frozen embryos, surgically split into duplicates, in order to make identical twins for a 42,000-year voyage to an earth-like planet orbiting a star 82 light years from earth. The scientists working on the project have reservations about their involvement in something that is obviously illegal and something many of them think is immoral also. Browne has put together an interesting story with good characterization of his main characters and a plot line that goes through many surprising twists and turns. The interesting part is that the government plans a simulation of the voyage in an underground facility with four unsuspecting children raised from birth to eighteen thinking they are on a real voyage through interstellar space. Once the government deems the simulation successful, the government plans to drug the children and move them to a hospital with a phony story.
