Relentless Moon (Lady Astronaut, Bk. 3)

While Elma York is on her way to Mars, her friends - the other Lady Astronauts - are playing their parts in establishing the lunar colony. Astronaut Nicole Wargin is flying supply missions, and doing her share of tours on the Moon to build the colony. Her husband, now the governor of Kansas, would rather she stayed at home. Myrtle Lindholm and her husband, both astronauts, are settlers on the Moon. Their rank and experience make them key to the colony's survival.

But politics on Earth are coming to the boiling point. There are food shortages due to the oncoming climate catastrophe. Riots and sabotage plague the space program. The International Aerospace Coalition's goal of getting as many people as possible off Earth before it becomes uninhabitable is being threatened.
