Hot Moon - Alan Smale - Bog

In an alternate 1979, the United States and the Soviet Union have permanent Moon bases, crewed spy satellites, and frequent hostilities. Vivian Carter, commander of Apollo 32, is on a mission to explore a volcanic region of the Moon when she is caught in the crossfire of a Soviet attack. Barely escaping, she and her crew are redirected to land at Hadley Base, a NASA outpost. Hadley Base, though, soon comes under attack, and the unarmed astronauts must find a way to defend themselves.
