Stranger in a Strange Land

It tells the story of Valentine Michael Smith, a human who has returned to Earth in early adulthood after being raised by Martians on the planet Mars.
The novel explores his interaction with—and the eventual transformation of—Earth culture. The title seems to be an allusion to the phrase in Exodus 2:22 (in the Biblical Book of Exodus).
According to Heinlein, the novel's working title was The Heretic. Several later editions of the book have promoted it as "The most famous Science Fiction Novel ever written."
