Friday by Robert A Heinlein (Books 2020, 14)
Friday Baldwin is genetically engineered ‘artificial person.’ Indistinguishable from a conventional human, she nonetheless is psychologically constrained by the way her society discriminates against her type.
That’s pretty much her only constraint, though. Her engineered nature also gives her enhanced strength, reflexes, sight, hearing, and smell, as well as genius-level intelligence. She starts out as a courier and soon becomes a fugitive.
This stands up pretty well, all these years since I first read it. The fragmented, Balkanised future North America is interesting. Easy travel everywhere by ‘tubes,’ which are presumably underground trains, and suborbital rockets. Corruption so pervasive that the characters don’t even notice it. You hand over your passport with ‘the appropriate squeeze’ folded inside it, and are waved through.
