''Beyond This Horizon'' is an science fiction novel by Creator/RobertAHeinlein first published as a serial in 1942.
!!This novel provides examples of:
* AuthorCatchphrase: Characters say "So?", with context making it clear it's meant in the sense of "Is that so?"
* DestructoNookie: The protagonist beats up his love interest; she returns the favor. True Romance.
* EvilutionaryBiologist: Subverted. The world government genetically engineers everybody for maximum genetic perfection (or, at least, elimination of imperfection), except for a carefully guarded population of "control naturals," and strongly encourages particularly hopeful genetic matches, as between the hero and heroine. The subversion is that this is presented as entirely a good thing. (This society is sometimes described as a "socialist" state but bears more in common with Technocracy. Everybody gets a small annual dividend from the output of the whole global economy as if it were a corporation in which all are stockholders; control naturals get a larger dividend, enough for a livable income, in compensation for their genetic inferiority and inability to compete with the average person.)
