"Invaders from the Infinite" by Jr. John W. Campbell is a science fiction novel published in 1961. The story follows three heroes—Arcot, Morey, and Wade—as they attempt to aid a race of superdogs in this sequel to earlier adventures. Campbell combines imaginative theoretical physics with space battles and futuristic technology. Critics note the novel's strength lies in its ingenious speculative science and novel artifacts, though the narrative includes extensive technical explanations and repeated combat sequences that showcase Campbell's inventive approach to early science fiction.
