Farnham's freehold

Farnham's Freehold is a science fiction novel by American writer Robert A. Heinlein. A serialised version, edited by Frederik Pohl, appeared in Worlds of If magazine (July, August, October 1964). The complete version was published in novel form by G.P. Putnam later in 1964. Farnham's Freehold is a post-apocalyptic tale. The setup for the story is a direct hit by a nuclear weapon, catapulting a nuclear shelter containing Farnham, his wife, son, daughter, daughter's friend, and employee into the future. While writing the story, Heinlein drew on his experience of building a fallout shelter under his home in Colorado Springs, Colorado in the 1960s.
