Invaders from the Infinite

Invaders from the Infinite, published in 1932, is a space opera by John W. Campbell that continues the adventures of the Arcot, Morey, and Wade trilogy. The novel pits Earth’s greatest scientific minds against cosmic threats and alien civilizations. Featuring faster-than-light travel, intergalactic warfare, and speculative technology, the book exemplifies early pulp science fiction. While dated in style and science, it reflects Campbell’s vision of human ingenuity and set the stage for his later influence as editor of Astounding Science Fiction.
