The Fated Sky

"Set in an alternate history where humanity establishes a colony on the moon, The Fated Sky follows Lady Astronaut Elma York as she works on rotation, flying shuttles between the moon and Earth. But, with the need to establish a foothold on Mars, the first exploratory mission is being planned without any women astronauts on the crew list. The problem? Mid-journey navigation calculations require a human computer, and all the computers are women. Follow Elma and her colleagues as they navigate gender barriers in the dangerous, uncharted territory of space travel."
