The Moon Maid
By Edgar Rice Burroughs
After a century of war, all Earth was at peace at last, and friendly communication had been established with the planet Mars. Interplanetary cooperation made possible what neither world had been able to achieve alone—ships to bridge the distance between the worlds. But The Barsoom, the first Earth-Mars vessel, was treacherously sabotaged, thrown off course, and forced to make an emergency landing inside the hollow Moon. And there, beneath the craters, at the interior of the arid satellite, the crew found a world cut off from the rest of the solar system, inhabited by warring races and the decaying remnants of an ancient civilization.
