Friday
Robert A. Heinlein
 The book's protagonist is Friday Baldwin, an artificial person both mentally and physically superior in many ways to an ordinary human, but she faces great prejudice and will most likely be killed if her "non-human" status is discovered. Employed as a highly self-sufficient combat courier, her various missions take her throughout the globe and also to some of the near-Earth space colonies. The novel is set in a complex, Balkanized world, and Friday is caught up in several civil disturbances during the course of her travels. She reaches her employer's home base safely but is soon displaced. Sent on a space journey as a courier, she realizes that the journey is likely to end with her death, evades the ship's authorities, and settles on a pioneer world with friends made earlier in the narrative.
