The Traveler The Day After continues the journey set forth in the first book The Traveler. A group of Earth evacuees crash land on a desolate planet. An unknown life form on the planet attacks them day and night. It is only by continually moving that they are able to survive. A large machine The Traveler is constructed from the remnants of their crashed craft. It has been in a constant state of reconstruction and addition for forty years. The machine is several stories tall and several blocks wide. Many lost their lives to build The Traveler and over time the population has grown to that of a small city. It's the unseen dangers that await them at every turn and not all of them are from the planet. This is part two of the story, and it picks up the next day as the survivors assess their situation. So many challenges yet to complete. What's next for Hawk and his friends?
