Triplanetary

In "Triplanetary," Edward E. Smith explores a hidden cosmic conflict between the alien races of the Arisians and Eddorians, set against the backdrop of Earth's history from ancient Rome to World War II. The narrative follows the secretive breeding of humans, particularly the Kinnison and MacDougall lines, intended as weapons in this intergalactic struggle. As the story unfolds, humanity begins to heal and unite with Arisian technology, forming the Triplanetary League to fend off threats from enemies on Jupiter. This engaging tale is rich in both action and the complexities of alien diplomacy.
