A comet hits the Earth in the year 3550 and the entire Earth is flooded by the poles melting. Everything under 6,000 feet of sea water is dead. Only two groups survive in northern America near Lake Tahoe, a Christian Church group and a Liberal Jewish Temple group. They meet and work together to survive; built many oil drum rafts and sail for high ground.
From the novel, “The 23rd Psalm,” Dr. Greenspan helps to save many people with his medical skills. This is a unique story of two religious groups seeking to survive after a Comet hits the Earth and the Poles melt. Combine the science fiction theme with a Messiah theme and you get the 23rd Psalm where each chapter is a line from the famous Prayer from the bible.
