Description: Farnham's Freehold is a post-apocalyptic tale, as the setup for the story is a direct hit by a nuclear weapon, which sends into the future a fallout shelter containing Farnham, his wife, son, daughter, daughter's friend, and black domestic servant. Heinlein drew on his experience in building a fallout shelter under his own house in Colorado Springs, Colorado in the 1960s. The book is popular with survivalist groups as it combines the civil engineering and physics of fallout shelter survival with the social dynamics of "lifeboat rules," or autocratic authority under extreme conditions, a theme further explored in depth in The Number of the Beast. To paraphrase Mr. Farnham, "How do you know who is the officer in the lifeboat? The one with the gun."
