The Relentless Moon

The Relentless Moon follows Nicole Wargin, a female astronaut and former spy, as she works on a lunar base in an alternate 1960s timeline where Earth faces an environmental catastrophe. When saboteurs target the space program, Nicole must balance her duties as an astronaut with investigating the mounting threats. The novel takes place parallel to the events of The Calculating Stars and continues the Lady Astronaut series' exploration of space colonization during an accelerated space race. The story combines elements of hard science fiction with espionage, while depicting the technical and social challenges of establishing a permanent lunar colony. Set against the backdrop of Earth's climate crisis, the narrative examines how humanity adapts to existential threats and the cost of survival. The book addresses themes of gender roles, political conflict, and the tension between personal sacrifice and duty.

🚀 The novel is part of the "Lady Astronaut" series that won the Hugo Award for Best Series in 2021, showcasing its significant impact on science fiction literature. 🌗 The author, Mary Robinette Kowal, consulted extensively with NASA engineers and astronauts to ensure technical accuracy in her depiction of space travel and lunar colonization. 👩‍🚀 The character Nicole Wargin was inspired by the Mercury 13 - a group of women who underwent the same physiological screening tests as male astronauts in the 1960s but were never allowed to fly in space. 🌍 The environmental catastrophe in the book's alternate timeline - a meteorite strike causing rapid climate change - was based on scientific models of actual extinction-level impact events. ✨ Kowal is not only an author but also a professional puppeteer who has worked with Jim Henson's Sesame Street and other productions, bringing a unique perspective to her character animations in prose.
