I finally got a copy of Heinlein’s Stranger in a Strange Land, that book famous enough to be name-checked by Billy Joel in We Didn’t Start the Fire. On the book’s cover, it bills itself as the most famous sci-fi novel. In a way, it was. It shocked conventional thought (par for Heinlein) and made college kids read sci-fi the way Tolkien did for fantasy.
I don’t want it made into a movie.
