The author could not find a realistic story of life on an interstellar spaceship, so he wrote one. Thirty-nine real life people leave Earth, travel through space for thirty years. Babies are born, the original adults die but not all of natural causes. The children must learn to control the ship, deal with the bodies of their dying parents and must load food from their accompanying warehouses onto their spaceship. Can the children, who have never flown on Earth, control the spaceship and successfully land once they arrive at their destination? Children born on the ship wonder what a planet is like.
