"If civilization were destroyed today- would John Thomas Rourke be able to Survive...?"
Survivalist Series by Jerry Ahern
Jerry Ahern (born in 1946) is a science fiction author best known for his post apocalyptic series The Survivalist. The books in this series are heavy with descriptions of the weapons the protagonists use to survive and prosecute a seemingly never ending war amongst the remnants of the superpowers from pre-apocalypse times. The series centers around the attempts of Dr. John Thomas Rourke, ex-CIA agent to preserve his family. In the first book, a nuclear war begins while Rourke is returning from a business trip. After surviving the crash of an airliner in the Southwest U.S., Rourke fights his way across the chaotic horror of the post-war United States to his retreat in Georgia, where he eventually reunites with his family.
Survivalist #10 begins a new phase - it takes place after Earth's atmosphere has been destroyed and Rourke and his family have been in cryogenic sleep for 500 years.
