Set eighty years in the future, this novel by the best-selling author Michael D. O'Brien is about an expedition sent from the planet Earth to Alpha Centauri, the star closest to our solar system. The Kosmos, a great ship that the central character Neil de Hoyos describes as a "flying city", is immense in size and capable of more than half light-speed. Hoyos is a Nobel Prize winning physicist who has played a major role in designing the ship. Hoyos has signed on as a passenger because he desires to escape the seemingly benign totalitarian government that controls everything on his home planet. He is a skeptical and quirky misanthropic humanist with old tragedies, loves, and hatreds that are secreted in his memory. The surprises that await him on the voyage-and its destination-will shatter all of his assumptions and point him to a true new horizon.
