Setting

Stranger in a Strange Land is set in a near-future version of Earth, likely sometime in the late 20th or early 21st century. While an exact year is not specified, the novel takes place after a fictional “Third World War” and depicts a world with advanced space travel capabilities, allowing for missions to Mars. The story primarily unfolds in the United States, with references to a global government called the Federation of Free States.

Key locations in the novel include Bethesda Hospital, where Valentine Michael Smith is initially held upon his return from Mars, and Jubal Harshaw's estate in the Pocono Mountains of Pennsylvania, which serves as a safe haven for Smith and his followers. The narrative also takes readers to various other settings across the United States, including a carnival where Smith briefly works as a magician.

As the story progresses, the focus shifts to the Church of All Worlds, founded by Smith. This fictional religious movement, blending elements of paganism, revivalism, and Martian philosophy, becomes central to the latter part of the novel. The church's activities and the societal reactions to its unconventional practices provide a backdrop for exploring themes of sexuality, spirituality, and social norms in this speculative future America.

Characters

• Valentine Michael Smith: The “Man from Mars,” who was born on Mars and raised by Martians. He arrives on Earth as a young adult with superhuman abilities and a completely alien perspective. Smith struggles to understand human culture while developing his own spiritual movement. His innocence and extraordinary powers make him both revered and feared as he transforms society.
• Gillian (Jill) Boardman: A nurse who helps Smith escape government custody. She becomes one of his closest companions and a central figure in his spiritual movement. Jill plays a key role in introducing Smith to human culture and practices.
• Jubal Harshaw: A famous author, lawyer, and doctor who provides sanctuary and guidance to Smith. He serves as a father figure and voice of reason, maintaining a skeptical distance from Smith's movement while supporting his independence. Harshaw becomes an unwilling patron saint of Smith's church.
• Ben Caxton: An investigative journalist who helps free Smith initially. He joins Smith's inner circle but remains somewhat skeptical of their developing social order.
• Anne: One of Harshaw's secretaries and a certified Fair Witness. She becomes an early follower of Smith's teachings.
• Dr. Mahmoud: A semanticist who learns the Martian language. He joins Smith's church while maintaining his Muslim faith.
• Patty Paiwonski: A tattooed circus performer who joins Smith's inner circle. She maintains ties to the rival Fosterite church.

About the author

Robert A. Heinlein (1907-1988) was one of the most influential and controversial science fiction authors of the 20th century. Often called the “dean of science fiction writers,” Heinlein helped elevate the genre from pulp magazines to mainstream literature. His works explored themes like individualism, libertarianism, and sexuality, frequently challenging social conventions of the time. Some of Heinlein's most famous novels include Stranger in a Strange Land, Starship Troopers, and The Moon is a Harsh Mistress.

Heinlein's writing career spanned nearly 50 years, during which he pioneered techniques like “indirect exposition” that allowed him to build complex fictional worlds without lengthy explanations. His stories often featured competent, self-reliant protagonists and explored how advances in science and technology might shape future societies. Heinlein was known for rigorously researching the scientific elements in his fiction, helping establish “hard science fiction” as a distinct subgenre. Heinlein was the first author named Grand Master by the Science Fiction Writers of America and won four Hugo Awards during his lifetime.

Beyond literature, Heinlein influenced the real-world space program and popular views on space exploration. Many astronauts cited Heinlein's juvenile novels as inspiration, and he served as a commentator during the Apollo 11 moon landing broadcast. His works have also inspired religious movements, polyamory advocates, libertarian thinkers, and technology pioneers in Silicon Valley.
