Revolte auf Luna

The Moon is a Harsh Mistress is a science fiction novel by Robert A. Heinlein about a Lunar colony's revolt against rule from Earth. It was published in 1966 and the year after it received the Hugo Award for best novel.

The novel is narrated by Manny, a one-armed computerman whose accidental discovery of the self-awareness of an intelligent computer named Mike ignites a revolution against the hated Lunar Authority. The wise Professor de la Paz, the beautiful rabble-rousing Wyoming Knott and Manny plot with their computer friend Mike to organize their fellow Loonies to liberate the Moon from Earth's control. Hazel Stone, a young girl "with no cushions" leads the Baker Street Irregulars (and later becomes Grandmother Hazel in The Rolling Stones).

The book is the origin of the acronym TANSTAAFL ("There Ain't No Such Thing As A Free Lunch"), and helped popularize the constructed language Loglan, which is mentioned in the story as being used for precise human-computer interaction.

The computer Mike is named after Mycroft Holmes, brother of Sherlock Holmes.
