A (best-selling) book by Robert Heinlein, first published in 1984, about the exploits of a young (and, the cover-art would have it, scantily clad) courier-spy-superwoman, the genetically engineered miss Friday Jones. As the world around her descends in to political chaos, she accepts a mercenary mission to space - only to find that her new empoyers intend it to be a suicide mission.
