In 2216 the world is run by bureaucratic artificial intelligences. Humanity wants for nothing. Life is good - no disease, no aging. Everyone is young and beautiful. Machines provide gourmet food, palatial housing, and AI-generated, extremely high-quality entertainment. No one works. Who would? Space exploration is nearly forgotten. Marion Michelle Morrison, 'M' seems to be the only person able to push aside this new opiate of the masses and leave Earth. If she wants to get outside the solar system, she just needs to learn the secret physics of the Charm Drive - and convince her ship to help her. When unknown forces throw her back to 1985, she must find a way to return and save the planet from an extinction-level event. Brad is a struggling young farmer in 1985. As if taking care of his ailing mother and sister, and their failing farm are not enough, a metal sphere larger than his house has crashed into one of his corn fields.
