The Moon Maid

Edgar Rice Burroughs ventures into darkest science fiction with this generations-spanning epic of alien conquest and civilizational collapse. When humanity finally reaches the Moon in the late twentieth century, they discover something terrible: an intelligent race called the Kalkars, who have been watching and waiting. A treacherous Earthman allies with these moon-dwelling tyrants, and the invasion begins. What follows is a catastrophic domino effect: technology fails, cities fall, and Earth spirals from global war into feudal darkness over centuries. But hope survives in the blood of one man. Admiral Julian 3rd knows he will be reborn, again and again, through the ages: as his grandson who first uncovers the horror inside the Moon, as Julian 9th who refuses to kneel before the conquerors, and as Red Hawk, the fierce warrior who leads humanity's final stand. Burroughs delivers a pulp masterpiece that is surprisingly bleak, tracing not just one battle but the entire arc of a world's fall and the stubborn flame of resistance that refuses to die.
