Having to move indoors away from the killing rays of the sun has forced the world to reevaluate its priorities. Because of an accident that fried the sky, humankind will never again walk freely out in the open. Most are resigned to living underground. Bill Smith is just an average guy living in one of the underground cities in the Freeland District in the old state of California. After some convincing, Bill finally accepts an invitation from a friend to take a trip in an old amusement park ride named the Lifeboat. When he finds himself helplessly trapped inside the mind of the ride's sentient biological computer, he must summon help from Christ to rid the machine of evil and destroy its brain before Satan gains control. But will God's messenger find a way to complete his mission or will evil triumph over good in the Lifeboat? In this entertaining post-apocalyptic science fiction novel, a man who becomes trapped inside a machine learns that he cannot defeat evil without help from Jesus Christ.
